• A. a, b, c and d
• B. a, c and d
• C. a, b and d

Answer 1

The correct option is D b, c and d

The generative cell of pollen grain divides by mitosis to produce two male gametes. Pollen grain has certain apertures called germ pores and in the region of germ pores, sporopollenin is absent.
The inner layer of pollen grains is called intine and is made up of cellulose and pectin. Pollen grains are haploid and represent the male gametophytes of angiosperms.
