In this species (Tradescantia zebrina), the guard cells of the stomata are green because they contain chlorophyll while the epidermal cells are chlorophyll-free and contain red pigments.
AI overview
Stomata are tiny pores found on plant leaves that allow gas exchange between the plant and the air. They are controlled by specialized guard cells that open and close to regulate when the plant takes in carbon dioxide and releases oxygen and water vapor.

In botany, a stoma (: stomata, from Greek στόμα, "mouth"), also called a stomate (: stomates), is a pore found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange between the internal air spaces of the leaf and the atmosphere. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that regulate the size of the stomatal opening.
