Question

Though very little water is required for the process of photosynthesis,why do we give so much water to plants?

Answer 1

Not so much water is required instead water has to be continuously replaced as plants lose lots of water through transpiration. As a reason the cells of the plant will be shrinked if there is water shortage. Plants require water not only for photosynthesis but needed to carry out other processes such as transportation and maintenance of turgidity of cells and also to obtain minerals from the soil.
