The opening and closing of stomata is due to b) osmosis.
- There are guard cells present in the stomata which are responsible for the opening and closing of stomata.
- When the concentration of a solvent i.e water is more in a leaf cell, the guard cells open so that water moves from the cell to the outer environment.
- When the concentration of water is less in the leaf cell, the guard cells close to prevent the loss of water.
- As osmosis is the the movement of water from a higher to lower concentration, hence the opening and closing of stomata is due to osmosis.
