the process of passing water through the surface of a plant's leaves respiration. Loss of water from a plant, mainly through the stomata (see stoma) of leaves. Darkness, internal water deficit, and extremes of temperature tend to close stomata and decrease transpiration; illumination, ample water supply, and optimum temperature cause stomata to open and increase transpiration. Its exact significance is disputed; its roles in providing the energy to transport water in the plant and in aiding dissipation of the sun's heat (by cooling through evaporation of water) have been challenged. Since stomatal openings are necessary for the exchange of gases, transpiration has been considered by some to be merely an unavoidable phenomenon that accompanies the real functions of the stomata
the passage of water vapor into the atmosphere through the vascular system of plants
The process by which water absorbed by plants, usually through the roots, is evaporated into the atmosphere from the plant surface, principally from the leaves
is the transfer of water from plants to the atmosphere; water is taken up by the roots of plants and released as water vapor by the leaves
The process by which water absorbed by plants, usually through the roots, is evaporated into the atmosphere from the plant surface From Glossary of Geology, 4th Edition, 1997, American Geological Institute
The process by which water in plants is transferred as water vapor to the atmosphere
The process by which water absorbed by plants (usually through the roots) is evaporated into the atmosphere from the plant surface (principally from the leaves)
The process in plants by which water vapor is released into the gaseous environment, primarily through stomata
The process in plants by which water is taken up by the roots and released as water vapor by the leaves The term can also be applied to the quantity of water thus dissipated (Source: Carbon Dioxide Information Analysis Center, 1990)
Water is continually being pumped upward through the plant in the xylem Once it reaches the leaves it is transpired through pores called stomata A typical plant will lose over ninety percent of the water absorbed by its roots through transpiration This makes plants highly susceptible to drought Plants (like the cacti) that evolved in arid climates have developed thick skins and have fewer surfaces (shorter stems and modified leaves) to protect against dehydration due to transpiration
The act or process of transpiring or excreting in the form of vapor; exhalation, as through the skin or other membranes of the body; as, pulmonary transpiration, or the excretion of aqueous vapor from the lungs
the transfer of water from the leaves of plants to water vapor in the atmosphere
The process by which plants return moisture to the air Plants take up water through their roots and then lose some of the water through pores in their leaves As hot air passes over the surface of the leaves, the moisture absorbs the heat and evaporates into the air
The passing of gases through fine tubes, porous substances, or the like; as, transpiration through membranes
the emission of water vapor from the leaves of plants the passage of gases through fine tubes because of differences in pressure or temperature the process of givng off or exhaling water vapor through the skin or mucous membranes
Transpiration is the act or process of giving off vapor containing waste product through the stomata of plant tissue or pores of the skin
Transpiration is the process of water loss from plants through stomata Stomata are small openings found on the underside of leaves that are connected to vascular plant tissues Some dry environment plants do have the ability to open and close their stomata Transpiration is a passive process largely controlled by the humidity of the atmospheric and the moisture content of the soil Of the transpired water passing through a plant only 1 % is used in the growth process Transpiration also transports nutrients from the soil into the roots and carries them to the various cells of the plant
Process in which water is absorbed by the root systems of a plant, moves up through the plant, passes through pores (stomata) in leaves, and then evaporates into the atmosphere as water vapor
The process by which water vapor escapes from the living plant, principally the leaves, and enters the atmosphere
process by which water that is absorbed by plants, usually through the roots, is evaporated into the atmosphere from the plant surface, such as leaf pores See evapotranspiration
When it transpires that something is the case, people discover that it is the case. It transpired that Paolo had left his driving licence at home As it transpired, the Labour government did not dare go against the pressures exerted by the City. = turn out
When something transpires, it happens. Some speakers of English consider this use to be incorrect. Nothing is known as yet about what transpired at the meeting
give off (water) through the skin come about, happen, or occur; "Several important events transpired last week" come to light; become known; "It transpired that she had worked as spy in East Germany" exude water vapor; "plants transpire" pass through the tissue or substance or its pores or interstices, as of gas
