Answer:
Correct Answer: D
Solution:
[d] Pollen grains contain the male gametophyte produced by meiosis of microspore mother cells that are located along the inner edge of the microsporangia.
The outer part of the pollen is exine, which is composed of a complex polymer, sporopollenin.
Inner part is intine.
The cell contains a vegetative cell which develops into the pollen tube and germ pore, and a generative cell (which is not degenerative) are also present.
