Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. It is a passive process that requires no energy expense by the …

transpiration, in botany, a plant’s loss of water, mainly through the stomata of leaves. Stomatal openings are necessary to admit carbon dioxide to the leaf interior and to allow oxygen to escape during …

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 transpiration.

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 excess water, …

Jun 12, 2018 · Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves. In order to understand evapotranspiration, let’s explore what …

Nov 19, 2025 · Transpiration is the process by which plants release excess water as water vapour through their stomata, stems, or other plant parts. Water is essential for normal cell functioning, and …

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.

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 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.

Since plants do not have membranes that are both permeable to CO 2 and impermeable to water, transpiration is an inevitable consequence of photosynthesis. To control water loss, plants are …
