Guard cells have chloroplasts while other epidermal cells lack in it. Shape of guard cells is different in monocots (dumb-bell) and dicots (bean), while epidermal cells are irregular in shape in both.

Monocot and dicot plants contain stomata in their leaves as well as in their stem. The major role of stomata is to facilitate the gas exchange. They also facilitate transpiration, which helps the absorption of water from the soil and the transport of water through the xylem. The size of the stomata is controlled by a pair of guard cells. The main difference between stomata of monocot and dicot plants is that the guard cells of the monocots are dumbbell-shaped whereas the guard cells of dicot plants are bean-shaped.
