Using your text book try to identify and compare the structures typically found in the leaves of plants.

Notice the dark green bodies within the various cells found in the images of cross sections of plants above and below; these are chloroplasts.

C4 plants like the corn examples below, have two types of photosythetic cells, which differ in form and function. Bundle-sheath cells surround the viens found in leaves. In C4 plants they are photosythetic in C3 plants they are non-photosynthetic. Both C3 and C4 plants have photosynthetic Mesophyll cells.
