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 …

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 …

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 …

Feb 17, 2023 · Transpiration is the biological process by which water is released in the air as water vapor through minute pores called stomata. It occurs through the aerial parts of the …

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 …

Jul 23, 2025 · What is Transpiration? Plants release the excess water through evaporation through different plant parts such as stems or the stomata present on the surface of the leaves …

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 …

Nov 4, 2024 · Transpiration in plants occurs through several distinct pathways, each playing a specific role in water movement and evaporation. These pathways are classified into four …

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 …
