62-475: Greening is also a general term for the appropriate selection and planting of plants on, in, or next to buildings and in public parks . The goal of greening is usually a combination of environmental benefits and improving the visual design of surfaces, for example, a green wall or green roof , as well as the creation of green spaces. This usually requires technical measures such as earthworks or supporting climbing plants. Furthermore, permanent care and irrigation

124-468: A small business or a room in someone's home (see small office/home office ), entire floors of buildings, and massive buildings dedicated entirely to one company. In modern terms, an office is usually the location where white-collar workers carry out their functions. In classical antiquity , offices were often part of a palace complex or a large temple. In the High Middle Ages (1000–1300),

186-483: A 3,000,000-square-foot (280,000 m ) building in Chicago, at the time the largest building in the world. The time and motion study , pioneered in manufacturing by F. W. Taylor and later applied to the office environment by Frank and Lillian Gilbreth , led to the idea that managers needed to play an active role in directing the work of subordinates to increase the efficiency of the workplace. F.W. Taylor advocated

248-515: A lot of concentration, or include many small meetings. Shared office : a compact, semi-private workspace designed for two or three individuals, facilitating both focused work and small group collaboration. Team room : an enclosed workspace for four to ten people; suitable for teamwork that may be confidential and demands frequent internal communication. Study booth : an enclosed workspace for one person; suitable for short-term activities that demand concentration or confidentiality. Work lounge :

310-1734: A lounge-like workspace for two to six people; suitable for short-term activities that demand collaboration and/or allow impromptu interaction. Touch down : an open workspace for one person; suitable for short-term activities that require little concentration and low interaction. Meeting spaces in an office typically use interactive processes, be they quick conversations or intensive brainstorming. There are six generic types of meeting spaces, each supporting different activities. Small meeting room : an enclosed meeting space for two to four people; suitable for both formal and informal interaction. Medium meeting room : an enclosed meeting space for four to ten people; suitable for both formal and informal interaction. Large meeting room : an enclosed meeting space for ten or more people; suitable for formal interaction. Small meeting space : an open or semi-open meeting space for two to four persons; suitable for short, informal interaction. Medium meeting space : an open or semi-open meeting space for four to ten persons; suitable for short, informal interaction. Large meeting space : an open or semi-open meeting space for ten or more people people; suitable for short, informal interaction. Brainstorm room : an enclosed meeting space for five to twelve people; suitable for brainstorming sessions and workshops. Meeting point : an open meeting point for two to four people; suitable for ad hoc, informal meetings. Support spaces in an office are typically used for secondary activities such as filing documents or taking breaks. There are twelve generic types of support spaces, each supporting different activities. Filing space : an open or enclosed support space for

372-435: A particular focus in this area of research due to the increasingly limited access to green spaces and nature. In urban areas, parents or guardians may favor playing indoors versus outdoors based on the perception of safety and concerns. For example, families who live farther away from green spaces are more likely to push for indoor activities because of close proximity to busy roads or construction sites. On average, children in

434-558: A pioneer in this field. A project between 1991 and 2011 and supported by, among others, the forests of German states provided 450,000 trees for the desert city of Beersheba . Another major reforestation (greening) project is China's Green Wall , which aims to reduce the increasing devastation of entire regions in the north and west of the People's Republic of China . These "green" qualities include, but are not limited to: Environmentally friendly companies such as Green Home have developed

496-551: A protective response. The first such plant receptors were identified in rice and in Arabidopsis thaliana . Plants have some of the largest genomes of all organisms. The largest plant genome (in terms of gene number) is that of wheat ( Triticum aestivum ), predicted to encode ≈94,000 genes and thus almost 5 times as many as the human genome . The first plant genome sequenced was that of Arabidopsis thaliana which encodes about 25,500 genes. In terms of sheer DNA sequence,

558-420: A range of physical and biotic stresses which cause DNA damage , but they can tolerate and repair much of this damage. Plants reproduce to generate offspring, whether sexually , involving gametes , or asexually , involving ordinary growth. Many plants use both mechanisms. When reproducing sexually, plants have complex lifecycles involving alternation of generations . One generation, the sporophyte , which

620-400: A result of the country's unique business culture. Japanese offices tend to follow open plan layouts in an 'island-style' arrangement, which promotes teamwork and top-down management. They also use uchi-awase (informal meetings) and ringi-sho (consensus systems) to encourage input on policies from as many groups throughout the office as possible. The main purpose of an office environment

682-433: A result, more office space was assigned to house their activities. The time-and-motion study , pioneered in manufacturing by F. W. Taylor (1856–1915), led to the "Modern Efficiency Desk" of 1915. Its flat top, with drawers below, was designed to allow managers an easy view of their workers. By the middle of the 20th century, it became apparent that an efficient office required additional control over privacy , and gradually

744-639: A rigorous approval policy that allows consumers to qualify each product based upon these criteria as they apply to specific product categories. Exposure to greening initiatives has proven to achieve great health benefits for people of all ages. Greening can alleviate stressors of an urban environment, providing more opportunities to experience tranquility, reduce noise, and induce cooling effects. Exposure to greening initiatives can benefit both physical and mental health and can lead to more environmental awareness. Greening includes habitat restoration, planting trees, food gardening and naturalization. Children have been

806-618: A semi-enclosed workspace for two to eight people; suitable for teamwork which demands frequent internal communication and a medium level of concentration. Cubicle : a semi-enclosed workspace for one person; suitable for activities that demand medium concentration and medium interaction. Office Pod : ideal for fostering privacy in today's bustling open-plan offices. It provides a cost-effective and efficient way to ensure privacy and continuity during conversations, calls, and video conferences. Private office : an enclosed workspace for one person; suitable for activities that are confidential, demand

868-625: A semi-open or enclosed support space where employees can take a break from their work. Locker area : an open or semi-open support space where employees can store their personal belongings. Smoking room : an enclosed support space where employees can smoke a cigarette. Library : a semi-open or enclosed support space for reading books, journals and magazines. Games room : an enclosed support space where employees can play games, such as pool or darts. Waiting area : an open or semi-open support space where visitors can be received and wait for their appointment. Circulation space : support space which

930-474: A simple solution and provide all of the former types of space. Workspaces in an office are typically used for conventional office activities such as reading, writing, and computer work. There are nine generic types of workspaces, each supporting different activities. Open office : an open workspace for more than ten people; suitable for activities that demand frequent communication or routine activities that need relatively little concentration. Team space :

992-404: Is diploid (with 2 sets of chromosomes ), gives rise to the next generation, the gametophyte , which is haploid (with one set of chromosomes). Some plants also reproduce asexually via spores . In some non-flowering plants such as mosses, the sexual gametophyte forms most of the visible plant. In seed plants (gymnosperms and flowering plants), the sporophyte forms most of the visible plant, and

1054-547: Is a similar process. Structures such as runners enable plants to grow to cover an area, forming a clone . Many plants grow food storage structures such as tubers or bulbs which may each develop into a new plant. Some non-flowering plants, such as many liverworts, mosses and some clubmosses, along with a few flowering plants, grow small clumps of cells called gemmae which can detach and grow. Plants use pattern-recognition receptors to recognize pathogens such as bacteria that cause plant diseases. This recognition triggers

1116-411: Is a space where the employees of an organization perform administrative work in order to support and realize the various goals of the organization. The word "office" may also denote a position within an organization with specific duties attached to it (see officer or official ); the latter is an earlier usage, as "office" originally referred to the location of one's duty. In its adjective form,

1178-480: Is currently seeing efforts by political figures to increase awareness and funding in greening. For example, U.S Rep. Nydia M, Velazquez (D-NY) introduced a bill that would allocate $ 500 million federal funds to plan, install and maintain green roofs at public schools in New York City. It would be overseen by the U.S. Department of Energy through a grant program. Gardens are a unique greening initiative, whether

1240-496: Is known as botany , a branch of biology . All living things were traditionally placed into one of two groups, plants and animals . This classification dates from Aristotle (384–322 BC), who distinguished different levels of beings in his biology , based on whether living things had a "sensitive soul" or like plants only a "vegetative soul". Theophrastus , Aristotle's student, continued his work in plant taxonomy and classification. Much later, Linnaeus (1707–1778) created

1302-513: Is to support its occupants in performing their jobs—preferably at minimum cost and with maximum satisfaction. Different people performing different tasks will require different office spaces, or spaces that can handle a variety of uses. To aid decision-making in workplace and office design, one can distinguish three different types of office spaces: workspaces, meeting spaces, and support spaces. For new or developing businesses, remote satellite offices and project rooms, or serviced offices , can provide

1364-464: Is usually necessary to maintain the greened environment. In some areas there are normative requirements for the planning and execution of the greening, for example roadsides greening. In soil bioengineering , plants with technical functions may be needed. Measures such as the recultivation of heaps, plantations as part of a compensatory measure or, in tiller forestry , the planting of vegetation are distinguished from greening. In professional parlance,

1426-594: The Antarctic flora , consisting of algae, mosses, liverworts, lichens, and just two flowering plants, have adapted to the prevailing conditions on that southern continent. Plants are often the dominant physical and structural component of the habitats where they occur. Many of the Earth's biomes are named for the type of vegetation because plants are the dominant organisms in those biomes, such as grassland , savanna , and tropical rainforest . Office An office

1488-706: The Cretaceous so rapid that Darwin called it an " abominable mystery ". Conifers diversified from the Late Triassic onwards, and became a dominant part of floras in the Jurassic . In 2019, a phylogeny based on genomes and transcriptomes from 1,153 plant species was proposed. The placing of algal groups is supported by phylogenies based on genomes from the Mesostigmatophyceae and Chlorokybophyceae that have since been sequenced. Both

1550-457: The carpels or ovaries , which develop into fruits that contain seeds . Fruits may be dispersed whole, or they may split open and the seeds dispersed individually. Plants reproduce asexually by growing any of a wide variety of structures capable of growing into new plants. At the simplest, plants such as mosses or liverworts may be broken into pieces, each of which may regrow into whole plants. The propagation of flowering plants by cuttings

1612-502: The cubicle system evolved. The word "office" stems from the Latin " officium " and its equivalents in various Romance languages . An officium was not necessarily a place, but often referred instead to human staff members of an organization, or even the abstract notion of a formal position like a magistrate. The elaborate Roman bureaucracy would not be equaled for centuries in the West after

1674-623: The eukaryotes that form the kingdom Plantae ; they are predominantly photosynthetic . This means that they obtain their energy from sunlight , using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll . Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular , except for some green algae. Historically, as in Aristotle's biology ,

1736-1003: The "chlorophyte algae" and the "streptophyte algae" are treated as paraphyletic (vertical bars beside phylogenetic tree diagram) in this analysis, as the land plants arose from within those groups. The classification of Bryophyta is supported both by Puttick et al. 2018, and by phylogenies involving the hornwort genomes that have also since been sequenced. Rhodophyta [REDACTED] Glaucophyta [REDACTED] Chlorophyta [REDACTED] Prasinococcales   Mesostigmatophyceae Chlorokybophyceae Spirotaenia [REDACTED] Klebsormidiales [REDACTED] Chara [REDACTED] Coleochaetales [REDACTED] Hornworts [REDACTED] Liverworts [REDACTED] Mosses [REDACTED] Lycophytes [REDACTED] [REDACTED] Gymnosperms [REDACTED] Angiosperms [REDACTED] Plant cells have distinctive features that other eukaryotic cells (such as those of animals) lack. These include

1798-741: The 18th century to suit the needs of large and growing organizations such as the Royal Navy and the East India Company . The Old Admiralty ( Ripley Building ) was built in 1726 and was the first purpose-built office building in Great Britain. As well as offices, the building housed a board room and apartments for the Lords of the Admiralty. In the 1770s, many scattered offices for the Royal Navy were gathered into Somerset House ,

1860-551: The Metropolitan Water Reclamation District of Greater Chicago implemented a greening initiative called The Space to Grow. Though the purpose of this initiative was to control flooding and stormwater, schools successfully replaced asphalt with green space because of generous program funding by the city. Installing green roofs on schools is an alternative way of increasing green space access for children, especially in urban areas. The United States

1922-1070: The United States spend about 1,000 hours a year in school. Therefore, schools are an excellent tool for greening initiatives that involve children in urban spaces. Habitat restoration, gardening, naturalization and rewilding efforts in schools provide children with the opportunity to connect with nature. In a study conducted in Finland, researchers found that adding green to the school yard increased passion for outdoor activity as well as creativity and spontaneity in 3 to 5 year old children. In Barcelona, Spain, school greening initiatives provided more opportunities for children to spend time outside and reduced inequities in residential access. In current efforts to limit exposure to COVID-19 and contact between individuals, school yards have become an even more important tool to promote social learning and education. Benefits of greening initiatives include electricity cost savings due to cooling technology of greening, improving

1984-864: The Viridiplantae, along with the red algae and the glaucophytes , in the clade Archaeplastida . There are about 380,000 known species of plants, of which the majority, some 260,000, produce seeds . They range in size from single cells to the tallest trees . Green plants provide a substantial proportion of the world's molecular oxygen; the sugars they create supply the energy for most of Earth's ecosystems and other organisms , including animals, either eat plants directly or rely on organisms which do so. Grain , fruit , and vegetables are basic human foods and have been domesticated for millennia. People use plants for many purposes , such as building materials , ornaments, writing materials , and, in great variety, for medicines . The scientific study of plants

2046-801: The amount of cytoplasm stays the same. Most plants are multicellular . Plant cells differentiate into multiple cell types, forming tissues such as the vascular tissue with specialized xylem and phloem of leaf veins and stems , and organs with different physiological functions such as roots to absorb water and minerals, stems for support and to transport water and synthesized molecules, leaves for photosynthesis, and flowers for reproduction. Plants photosynthesize , manufacturing food molecules ( sugars ) using energy obtained from light . Plant cells contain chlorophylls inside their chloroplasts, which are green pigments that are used to capture light energy. The end-to-end chemical equation for photosynthesis is: This causes plants to release oxygen into

2108-431: The atmosphere. Green plants provide a substantial proportion of the world's molecular oxygen, alongside the contributions from photosynthetic algae and cyanobacteria. Plants that have secondarily adopted a parasitic lifestyle may lose the genes involved in photosynthesis and the production of chlorophyll. Growth is determined by the interaction of a plant's genome with its physical and biotic environment. Factors of

2170-467: The basis of the modern system of scientific classification , but retained the animal and plant kingdoms , naming the plant kingdom the Vegetabilia. When the name Plantae or plant is applied to a specific group of organisms or taxa , it usually refers to one of four concepts. From least to most inclusive, these four groupings are: There are about 382,000 accepted species of plants, of which

2232-500: The central office each day. As the Industrial Revolution intensified in the 18th and 19th centuries, the industries of banking , rail , insurance , retail , petroleum , and telegraphy dramatically grew in size and complexity. Increasingly large number of clerks were needed to handle order processing, accounting, and document filing, and these clerks needed to be housed in increasingly specialized spaces. Most of

2294-418: The desks of the era were top-heavy and had a cubicle-like appearance, with paper storage bins extending above the desk-work area, offering workers some degree of privacy. The relatively high price of land in the central core of cities led to the first multi-story buildings, which were limited to about 10 stories until the use of iron and steel allowed for higher structures. The first purpose-built office block

2356-488: The development of forests in swampy environments dominated by clubmosses and horsetails, including some as large as trees, and the appearance of early gymnosperms , the first seed plants . The Permo-Triassic extinction event radically changed the structures of communities. This may have set the scene for the evolution of flowering plants in the Triassic (~ 200  million years ago ), with an adaptive radiation in

2418-451: The environment, providing healthy educational space, and more learning opportunities. It can help alleviate the stressors associated with urban climates and benefit both mental and physical health of children. Schools increase the total green space by adding green oases in yards and replacing pavement with vegetation. In Paris, schools have adopted this intervention as a cooling program for schools. Chicago’s Department of Water Management and

2480-401: The existence of such "offices". These rooms are sometimes called "libraries" by some archaeologists because of scrolls' association with literature. They were, however, closer to modern offices because the scrolls were meant for record-keeping and other management functions, not for poetry or works of fiction. The High Middle Ages (1000–1300) saw the rise of the medieval chancery , which was

2542-479: The fall of Rome , with areas partially reverting to illiteracy. Further east, the Byzantine Empire and varying Islamic caliphates preserved a more sophisticated administrative culture. Offices in classical antiquity were often part of a palace complex or a large temple. There was often a room where scrolls were kept and scribes did their work. Ancient texts mentioning the work of scribes allude to

2604-542: The first block purpose-built for office work. The East India House was built in 1729 on Leadenhall Street as the headquarters from which the East India Company administered its Indian colonial possessions . The Company developed a very complex bureaucracy for the task, necessitating thousands of office employees to process the required paperwork. The Company recognized the benefits of centralized administration and required that all workers sign in and out at

2666-409: The gametophyte is very small. Flowering plants reproduce sexually using flowers, which contain male and female parts: these may be within the same ( hermaphrodite ) flower, on different flowers on the same plant , or on different plants . The stamens create pollen , which produces male gametes that enter the ovule to fertilize the egg cell of the female gametophyte. Fertilization takes place within

2728-716: The goal is to grow vegetables, fruit or flowers. For example, in Brookline, Massachusetts, United States, the Florida Riffin Ridley School has a vegetable garden that is maintained by teachers, students and parents. A garden intervention may positively influence children’s food preference, increase intake of fruits and vegetables, and increase physical activity. Plants can be added to offices and workspaces to aid in focus, reduce stress levels, increase creativity, improve air quality , and provide aesthetic appeal. Plants See text Plants are

2790-583: The great majority, some 283,000, produce seeds . The table below shows some species count estimates of different green plant (Viridiplantae) divisions . About 85–90% of all plants are flowering plants. Several projects are currently attempting to collect records on all plant species in online databases, e.g. the World Flora Online . Plants range in scale from single-celled organisms such as desmids (from 10  micrometres   (μm) across) and picozoa (less than 3 μm across), to

2852-564: The invention of the printing press and its wider distribution, there was often no clear cultural distinction between a private office and a private library ; books were both read and written at the same desk or table , as were personal and professional accounts and letters. During the 13th century, the English word "office" first began to appear when referring to a position involving specific professional duties (for example, "the office of the....") Geoffrey Chaucer appears to have first used

2914-529: The land 1,200  million years ago , but it was not until the Ordovician , around 450  million years ago , that the first land plants appeared, with a level of organisation like that of bryophytes. However, fossils of organisms with a flattened thallus in Precambrian rocks suggest that multicellular freshwater eukaryotes existed over 1000 mya. Primitive land plants began to diversify in

2976-412: The large water-filled central vacuole , chloroplasts , and the strong flexible cell wall , which is outside the cell membrane . Chloroplasts are derived from what was once a symbiosis of a non-photosynthetic cell and photosynthetic cyanobacteria . The cell wall, made mostly of cellulose , allows plant cells to swell up with water without bursting. The vacuole allows the cell to change in size while

3038-515: The largest trees ( megaflora ) such as the conifer Sequoia sempervirens (up to 120 metres (380 ft) tall) and the angiosperm Eucalyptus regnans (up to 100 m (325 ft) tall). The naming of plants is governed by the International Code of Nomenclature for algae, fungi, and plants and the International Code of Nomenclature for Cultivated Plants . The ancestors of land plants evolved in water. An algal scum formed on

3100-665: The late Silurian , around 420  million years ago . Bryophytes, club mosses, and ferns then appear in the fossil record. Early plant anatomy is preserved in cellular detail in an early Devonian fossil assemblage from the Rhynie chert . These early plants were preserved by being petrified in chert formed in silica-rich volcanic hot springs. By the end of the Devonian, most of the basic features of plants today were present, including roots, leaves and secondary wood in trees such as Archaeopteris . The Carboniferous period saw

3162-453: The medieval chancery acted as a sort of office, serving as the space where records and laws were stored and copied. With the growth of large, complex organizations in the 18th century, the first purpose-built office spaces were constructed. As the Industrial Revolution intensified in the 18th and 19th centuries, the industries of banking , rail , insurance , retail , petroleum , and telegraphy grew dramatically, requiring many clerks. As

3224-655: The midpoint of the 20th century, it became apparent that an efficient office required more privacy in order to combat tedium, increase productivity, and encourage creativity. In 1964, the Herman Miller (office equipment) company contracted Robert Propst , a prolific industrial designer. Propst came up with the concept of the Action Office , which later evolved into the cubicle office furniture system. Offices in Japan have developed unique characteristics partly as

3286-501: The physical or abiotic environment include temperature , water , light, carbon dioxide , and nutrients in the soil. Biotic factors that affect plant growth include crowding, grazing, beneficial symbiotic bacteria and fungi, and attacks by insects or plant diseases . Frost and dehydration can damage or kill plants. Some plants have antifreeze proteins , heat-shock proteins and sugars in their cytoplasm that enable them to tolerate these stresses . Plants are continuously exposed to

3348-665: The place where most government letters were written and laws were copied within a kingdom. The rooms of the chancery often had walls full of pigeonholes, constructed to hold rolled-up pieces of parchment for safekeeping or ready reference. This kind of structure was a precursor to the modern bookshelf. The introduction of the printing press during the Renaissance did not impact the setup and function of these government offices significantly. Medieval paintings and tapestries often show people in their private offices handling record-keeping books or writing on scrolls of parchment . Before

3410-538: The plant kingdom encompassed all living things that were not animals , and included algae and fungi . Definitions have narrowed since then; current definitions exclude the fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants ( hornworts , liverworts , mosses , lycophytes , ferns , conifers and other gymnosperms , and flowering plants ). A definition based on genomes includes

3472-469: The smallest published genome is that of the carnivorous bladderwort ( Utricularia gibba) at 82 Mb (although it still encodes 28,500 genes) while the largest, from the Norway spruce ( Picea abies ), extends over 19.6 Gb (encoding about 28,300 genes). Plants are distributed almost worldwide. While they inhabit several biomes which can be divided into a multitude of ecoregions , only the hardy plants of

3534-484: The sowing or planting of agricultural crops is also referred to as crop growing or occasionally as field cultivation. The term sowing is used for lawns . The greening of deserts is a particularly difficult task. If it is sustainable, it is the most effective measure for the economic development of arid areas, decreases global warming , and also improves the local climate . The state of Israel in Negev has long been

3596-523: The storage of frequently used files and documents. Storage space : an open or enclosed support space for the storage of commonly used office supplies. Print and copy area : an open or enclosed support space with facilities for printing, scanning and copying. Mail area : an open or semi-open support space where employees can pick up or deliver their mail. Pantry area : an open or enclosed support space where employees can get refreshments and where supplies for visitor hospitality are kept. Break area :

3658-412: The term "office" may refer to business -related tasks. In law , a company or organization has offices in any place where it has an official presence, even if that presence consists of a storage silo , for example, instead of a more traditional establishment with a desk and chair . An office is also an architectural and design phenomenon, including small offices, such as a bench in the corner of

3720-537: The use of large, open floor plans and desks that faced supervisors. As a result, in 1915, the Equitable Life Insurance Company in New York City introduced the "Modern Efficiency Desk" with a flat top and drawers below, designed to allow managers an easy view of the workers. This led to a demand for large square footage per floor in buildings, and a return to the open spaces that were seen in pre–industrial revolution buildings. However, by

3782-709: The word in 1395 to mean a place where business is transacted in The Canterbury Tales . As mercantilism became the dominant economic theory of the Renaissance , merchants tended to conduct their business in buildings that also sometimes housed people doing retail sales, warehousing, and clerical work. During the 15th century, the population density in many cities reached a point where merchants began to use stand-alone buildings to conduct their business. A distinction began to develop between religious, administrative/military, and commercial uses for buildings. The first purpose-built office spaces were constructed in
