Solution:

The wall of pollen grain has two layers, outer exine and inner intine. Intine is pecto-cellulosic in nature. Exine is made of a highly resistant fatty substance called sporopollenin. The point at which funicle touches the ovule is known as hilum. A raphe is formed by the fusion of funiculus with the body of ovule.
