The rate of transpiration in plants is affected by several factors, including temperature, evaporationhumidhumidityincreaseslightstomatawind, wind and light intensity.
At higher temperatures, evaporationhumidhumidityincreaseslightstomatawind and thus transpiration increases.
When the air is evaporationhumidhumidityincreaseslightstomatawind, diffusion of water vapour out of the leaf slows down and transpiration decreases.
When evaporationhumidhumidityincreaseslightstomatawind speed increases, faster moving air removes water vapour, increasing the rate of diffusion of water vapour from the leaf. Transpiration evaporationhumidhumidityincreaseslightstomatawind.
When evaporationhumidhumidityincreaseslightstomatawind intensity increases, the evaporationhumidhumidityincreaseslightstomatawind open wider to allow more carbon dioxide into the leaf for photosynthesis, leading to increased transpiration.
