Describe opening of stomata^^ ! ! ! !

Mechanism of opening and closing of stomata 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 turgid due to water accumulation in them which results in the opening of the guard cells. Closing of stomata: As the somata open the solute concentration is reduced. This makes the water from the guard cells to move away into neighbouring cells. Now, guard cells becom flaccid with no water. They collapse against each other and result in the closing of stomata.
Answer:
As we know stomata are the tiny pores present on the surface of the leaves.stomata runs the process of transpiration,which leads to loss of large amount of water.the opening and the closing of the pore is a function of the guard cells.the guard cells swell when water flows into them,causing the stomatal pore to open. Similarly pore closes when guard cell shrinks.
