Question

Which of the following statements regarding pollen grain is correct?

• A. Tapetum nourishes the developing pollen.
• B. Sporogenous tissue in the anther is haploid.
• C. Endothecium produces the micro spores.
• D. Only pollen cannot produce a complete plant in any condition.

Answer 1

The correct option is A Tapetum nourishes the developing pollen.

The tapetum is a layer of multinucleated cells surrounding the microsporogenous tissue. This is the layer which provides nutrition to the microsporogenous tissue and the developing microspores.

The sporogenous tissue is diploid and undergoes meiotic division to produce haploid microspores.

The pollen cannot produce a new plant. There are male gametes in the pollen which fuse with the female gametes to form the embryo which develops to form the new plant.

Thus, the correct answer is option A.
