Detailed explanation-1: -Stomata regulate the opening and. closing of guard cells. If the cells didn’t function, photosynthesis and transpiration would cease, which would interfere with the necessary continuous flow of water upward from roots to leaves.
Detailed explanation-2: -Because plants must exchange gases through their stomata, closing them prevents plants from taking up carbon dioxide (CO2). Without CO2, plants cannot make carbohydrates, and plants can only obtain this critical molecule when stomata are open.
Detailed explanation-3: -Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is ‘pulled’ into the leaves.
Detailed explanation-4: -Permanent wilting occurs when there isn’t enough water in the soil for a plant’s roots to access. As cells dry out and shrink, they lose their firmness and go floppy as a result.
Detailed explanation-5: -If plants are losing water faster than they are gaining it, the stomata close.
