How can plants be grown under a limited water supply without compromising on metabolic activities?
Water plays a vital role in photosynthesis by providing hydrogen for the synthesis of glucose and releasing oxygen as a byproduct. Additionally, it helps maintain cell turgor, which is essential for structural support and the proper functioning of cellular processes. Changes in the water level cause physiological changes in the plant. Transpiration is reduced, and leaves might wilt to conserve water and reduce loss. Thus normal metabolic activities can be continued despite the water shortage.
