Date of investigation: 22nd May 2001 Title: Transpiration Question: What factors affect the rate of transpiration. Factors: Various environmental factors affect the rate of transpiration in a plant. Here are a few: - Temperature A temperature increase means that the water will evaporate more rapidly from the leaves of a plant causing more water to be absorbed through the roots. The thermal energy also helps to make the chemical reaction between carbon dioxide and water happen more often to make glucose more efficiently. As photosynthesis only use's 1%-2% of the water taken out by the roots this causes little change on the rate of transpiration. Availability of water The plant will have trouble transpiring steadily if the amount of water loss is more then the uptake of water by the plant. If the rate of transpiration exceeds the absorption of water, loss of turgor occurs. (The explanation of turgid can be found in my background information.) As a...
