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 plant. [1] Transpiration also cools plants, changes osmotic pressure of cells, and enables mass flow of mineral nutrients.

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, and it leaves the plant through transpiration.

Jan 25, 2025 · 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 photosynthesis.

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 plant, such as leaves, stems, and flowers. It happens during daytime when leaves absorb sunlight and get heated up causing water to evaporate from its surface.

This process of elimination of excess water from the plant body is known as transpiration. It is generally the evaporation of water from the surface of the leaves. During the process of transpiration, water molecules in the plant tissues are removed from the aerial parts of the plants.

What is transpiration? In actively growing plants, water is continuously evaporating from the surface of leaf cells exposed to air. This water is replaced by additional absorption of water from the soil.

Transpiration refers to the loss of water vapor through plant stomata, mainly in the leaves. Hot, dry, and windy conditions increase transpiration rate.

Jun 20, 2021 · The process of loss of water in the form of vapor through the exposed aerial parts of the plants is called transpiration. Transpiration is regulated by vital activities of protoplasm and some structural peculiarities of the transpiring organs. Why …

Transpiration is defined as the physiological loss of water in the form of water vapor, mainly from the stomata in leaves, but also through evaporation from the surfaces of leaves, flowers, and stems. There are three main types of transpiration, based on where the process occurs:

Transpiration also provides the driving force for transport of water and nutrients from roots to shoots. Consequently, transpiration processes affect the yield and survival of agricultural species, and impact on the global carbon and hydrological cycles.
