Answer: special cells covering stomatal openings are guard cells
Explanation:
Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata.
Guard cells are specialized cells in the epidermis of leaves, stems and other organs that are used to control gas exchange.
The guard cells are produced in pairs with a gap between them that forms a stomatal pore. The stomatal pores are largest when water is freely available and the guard cells are turgid and closed when water availability is critically low and the guard cells become flaccid.
