Answer:
1. these are epidermal cells.
2. these surround the guard cells or we can also say stomata. they play a role in active potassium pump mechanism.
3. these are guard cells.
4. these guard cells surround the stomata and controls its opening and closing.
During night the absasic acid acts on guard cells and interfears the K+ and H+ exchange. by which they become flaccid and causes the stomatal pore to close.
