2019年10月4日 · Transpiration Definition. Transpiration is the evaporation of water from plants. Most of the water absorbed by the roots of a plant—as much as 99.5 percent—is not used for growth or metabolism; it is excess water, and it leaves the plant through transpiration. Transpiration is very important for maintaining moisture conditions in the ...
Transpiration | Definition, Mechanism, & Facts | Britannica
Transpiration, in botany, a plant’s loss of water, mainly though the stomata of leaves. Stomata are necessary to admit carbon dioxide for photosynthesis and to release oxygen. Hence, transpiration is generally considered to be merely an unavoidable phenomenon that accompanies the real functions of the stomata.
Transpiration – Definition, Factors, Types, and Importance
2023年2月17日 · Stomatal transpiration (through leaves) – Loss of water through specialized pores present in the lower surface of leaves called stomata.It accounts for around 80 to 90% of the total water loss from plants. Cuticular transpiration (through leaves and stem) – The water lost through the impermeable covering present on the leaves and stem of the plant called the cuticle.
Transpiration - What and Why? | Transpiration - Water …
It is thought that transpiration enhances nutrient uptake into plants. Carbon dioxide entry: When a plant is transpiring, its stomata are open, allowing gas exchange between the atmosphere and the leaf. Open stomata allow water vapor to leave the leaf but also allow carbon dioxide (CO 2) to enter. Carbon dioxide is needed for photosynthesis to ...

Transpiration in plants is a crucial process. In the absence of transpiration, excess water will get accumulated in the plant cells, and the cells will eventually burst. More than 10% of the earth’s moisture is from transpiration. It is known to be a part of the water cycle. Also Read: Transportation in Plants

2023年5月27日 · Transpiration is very vital to plants because it supports various important functions. It distributes water and nutrients from the roots to the aerial portions, promoting growth and metabolic activities of the plants. Transpiration also aids in cooling and temperature regulation in plants.
