Transpiration - What and Why? What is transpiration? In actively growing plants, water is continuously evaporating from the surface of leaf cells exposed to air. This water is replaced …

The process of transpiration keeps the cell turgid, cools the surface of the leaves, and helps in the movement of minerals from the soil to different parts of the plant.

Oct 4, 2019 · 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 …

Transpiration is the evaporation of water from plants. It occurs chiefly at the leaves while their stomata are open for the passage of CO 2 and O 2 during photosynthesis.

The atmosphere to which the leaf is exposed drives transpiration, but also causes massive water loss from the plant. Up to 90 percent of the water taken up by roots may be lost through …
