WebThe environmental factors affecting the rate of transpiration are: Light, Humidity, Temperature, Atmospheric pressure, Wind speed or velocity. Relative Humidity The amount of water vapour present in the air at a … Web1. Atmospheric Humidity: The rate of transpiration is roughly inversely proportional to atmospheric humidity. As the outward diffusion of water vapors through stomata is in accordance with the law of simple diffusion, the rate of transpiration is greatly reduced when the atmosphere is very humid.

Transpiration Definition, Mechanism, & Facts Britannica

WebAs wind speed increases, plants react by upping their rate of transpiration, which is the plant’s loss of water as it’s absorbed through the roots, up to the leaves, and out the leaves as it evaporates. More than 90 percent of the water a plant absorbs is lost by transpiration. It’s inevitable with photosynthesis. WebJan 25, 2024 · Transpiration helps in the elimination of excess water. It is an inevitable process and a necessary evil. The factors affecting the rate of transpiration are divided into two types- external and internal factors.
