A) Hard outer layer of pollen is called intone
B) Sporogenous tissue is haploid
C) Endothelium produces the microspores
D) Tarentum nourishes the developing pollen
Correct Answer: D
Solution :
Tapetum is the innermost layer of microsporangium. It nourishes the pollen grains. The inner wall of pollen grain is called inline. Endothelium is the wall around the microsporangium, which provide protection and help in dehiscence of anther to release the pollen. Sporogenous tissue is diploid. It undergoes meiotic division to form microspore tetrads.
