Question

explain the mechanism of closing and opening of the stomata​

Answer 1

Answer:

Mechanism of opening and closing of stomata The opening of stomata: Solutes from neighbouring epidermal and mesophyll cells enter the guard cells lowering its osmotic potential and water potential. This lowered water potential and osmotic potential will allow movement of water into guard cells from neighbouring cells. Guard cells become turbid due to water accumulation in them which results in the opening of the guard cells. The closing of stomata: As the stomata open the solute concentration is reduced. This makes the water from the guard cells to move away into neighbouring cells. Now, guard cells become flaccid with no water. They collapse against each other and result in the closing of stomata.
