Exine and intine are parts of a B. Pollen grain.

In a pollen grain, the exine is the outermost layer, and it is made of a tough substance called sporopollenin. The intine, on the other hand, is the inner layer of the pollen grain. These two layers play important roles in protecting and facilitating the transport of male gametes (sperm cells) during the process of plant reproduction.
