Question

Which one of the following statement 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

Answer 1

The correct option is D

Tapetum nourishes the developing pollen

Tapetum is the innermost layer of microsporangium. It nourishes the pollen grains. The inner wall of the 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. The sporogenous tissue is diploid. It undergoes meiotic division to form microspore tetrads.
