The rate of transpiration increase by every 10 degree centigrade increase in temperature. But, at the 40 to 45 degree centigrade, the stomata closed and rate of transpiration stop. Plants discharge water by different parts of body which are explain below, Lentcular Cells The cells which are present on stem between bark layers are known as lenticular cells. Only 1 to 2% water  release by lenticular cells. Cuticle Cells Cuticle cells are present on leaf and play important role in transpiration. Only 5 to 7% water release through these cuticle cells. Stomata Cells Stomata also play great role in transpiration. 90% water transport through these cells. Tobacco Plant contains 14000 stomata. 40% transpiration takes place through leaf. Guttation In small plants such as grass...
