Why is the inner wall of the guard cell facing the stomatal pore is thicker than the outer wall

Expert Answer:

The inner walls of the guard cells are thick to facilitate the opening of stomatal pore during transpiration. When water enters, outer walls expand which cause the inner walls to draw out causing opening of stomata.
