Which one of the following statement is correct?

Options

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.

Answer

D

Explanation

Tapetum is the innermost layer of microsporangium. It nourishes the pollen grains. The inner wall of pollen grains 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.
