Step-by-step solution
The given figure illustrates the structure of a stomatal apparatus. Label 'X' points to one of the two bean-shaped cells that enclose the stomatal pore. These are the guard cells, which contain chloroplasts and are responsible for regulating the opening and closing of the stoma.
