Q. Which one of the following statements is correct?
A) Hard outer layer of pollen is called intine
B) Sporogenous tissue is haploid
C) Endothecium produces the microspores
D) Tapetum nourishes the developing pollen
Explanation
[Solution from source] The tapetum, the innermost wall layer of the microsporangium, nourishes the developing pollen grains. The hard outer pollen layer is the exine (intine is inner), sporogenous tissue is diploid, and microspores come from the sporogenous tissue, not the endothecium. Answer (4).
