Differentiate between Transpiration and Evaporation |
|
Answer» Transpiration is the evaporation of water from the aerial parts of plants, especially leaves but also stems flowers and roots. Leaf surface are dotted with openings called stoma that are bordered by guard cells. Collectively these structures are called stomata. Leaf transpiration occurs through stomata and can be thought of as a necessary cost associated with the opening of the stomata to allow the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants and enables mass flow of mineral nutrients and water from roots to shoots. |
