Detailed explanation-1: -Guard cells. Hint: Chloroplast is the double membrane bounded green colour subcellular plant organelle which is a type of plastid, it performs photosynthesis due to presence of a green colour pigment called chlorophyll that captures the radiant energy which comes from the sun.
Detailed explanation-2: -Guard cells are another type of plant single-cell models to study early signal transduction and stress tolerance mechanisms in plants. Guard cells are surrounded by stomatal pores and are located in leaf epidermis. Guard cells control influx and efflux of CO2 and water from leaves, respectively.
Detailed explanation-3: -Guard cells are cells surrounding each stoma. They help regulate the opening and closing of the stoma. When the guard cells are turgid or swollen, the stomatal opening is large and when the guard cells have lost water or flaccid, the stomatal opening closes.
