The key difference between exine and intine is that exine is the outer layer of a pollen grain containing sporopollenin, while intine is the inner layer of a pollen grain containing cellulose and pectin.
Pollen is the actual male gametophyte of seed plants. It is a reduced form of the gametophyte. Also, pollen is a single cell. Further, it contains male reproductive cells of these plants. Moreover, anthers bear pollens in sacs and via pollination pollens deposit on the stigma of flowers. Besides, there are two layers that surround the interior of the pollen. They are exine and intine. The exine is harder, thicker and more resistant than the inner layer: intine.
