A) Hard outer layer of pollen is called inline
B) Sporogenous tissue is haploid
C) Endothecium produces the microspores
D) Tapetum 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 intine. Endothecium 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.
