Cells which control the transpiration rate of plants are
Stomatal cells
Chlorophyll cells
Guard cells
Epidermal cells
Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata.
The stomatal pore is guarded by two kidney shaped guard cells. Name the epidermal cells surrounding the guard cells. How does a guard cell differ from an epidermal cell? Use a diagram to illustrate your answer.
Draw a neat diagram of the stomatal apparatus found in the epidermis of leaves and label the Stoma, Guard cells, Chloroplast, Epidermal cells, Cell wall and the Nucleus.
