- Guard cells are specialized plant cells in the epidermis of leaves, stems and other organs that are used to control gas exchange.
- When the stomata are open, water is lost by evaporation and must be replaced via the transpiration stream, with water taken up by the roots.
- They 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 turgid, and closed when water availability is critically low and the guard cells become flaccid.
