	Guard cell	Epidermal cell
1	In surface view, guard cells resemble a bean.	Epidermal cells are irregular in shape.
2	The only epidermal cells capable of producing sugar are guard cells.	Epidermal cell do not produce sugar
3	The guard cells have chloroplasts, which allow them to produce food through photosynthesis.	Chloroplasts are not found in epidermal cells.
