WebHow does canopy structure affect transpiration? Canopy structure in trees is that portion of tree which is at the top. Canopy structure plays a role in transpiration and eventually ascent of sap. If leaves are exposed to sunlight then transpiration would be high and if they are covered by the canopy of the tree the transpiration would be low. WebJun 21, 2016 · My research shows that extreme air and soil temperature can alter the water transport rate from the soil into the root and plant system, which can reduce plant transpiration rate where plant transpiration … horse named scout tontoWebTranspiration is a necessary process and uses about 90% of the water that enters a plant's roots. The other 10% is used in chemical reactions and in plant tissues. Transpiration is responsible for several things: Transporting minerals from the soil throughout the plant.
