Transpiration is very important for maintaining moisture conditions in the environment. transpiration, in botany, a plant’ s loss of water, mainly through the stomates of leaves. powered by oxford dictionaries. what are the different steps of transpiration? stomatal transpiration. scrabble points: 15. transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.
more definitions, origin and scrabble points leaf surfaces are dotted with pores called stomata ( singular " stoma" ), and in. the meaning of transpiration is the act or process or an instance of transpiring; especially : the passage of watery vapor from a living body ( as of a plant) through a membrane or pores. 5% is lost by transpiration and guttation. what is transpiration and why is it important? 5 percent— is not used for growth or metabolism; it is excess water, and it leaves the plant through transpiration. namely, stomatal transpiration- when it occurs through the stomata. transpiration is of three types, based on the mode of water loss. transpiration is the evaporation of water from plants. transporting mineral ions. the remaining 97– 99.

light: the presence of light favours the opening of stomata and transpiration takes place through them. the rate of transpiration is always affected transpiration by a group of environmental factors like light, temperature, wind, atmospheric humidity, atmospheric pressure, availability of soil water, anti- transpirants. it is the evaporation of water from the stomata of the plants. in its most common usage, however, transpiration refers to the loss of water from plant foliage, occurring through microscopic pores known as stomata. most of the water absorbed by the roots of a plant — as much as 99. stomatal openings are necessary to admit carbon dioxide to the leaf interior and to allow oxygen to escape during photosynthesis, hence transpiration is generally considered to be merely an unavoidable phenomenon that accompanies the real functions of the stomates. maximum transpiration is done by stomata in plants, cuticular transpiration where water loss is through the waxy layer called cuticles in plants, and lenticular transpiration occurring through the lenticels of the plants.
