Question

Middle layers of anther wall.

• A. Persist in one layer at maturity
• B. Shrivel at maturity
• C. Help in development of pollen grains by nourishing them
• D. Become polyploidy at maturity

Answer 1

The correct option is A Persist in one layer at maturity

A. Persist in one layer at maturity

EXPLANATION: The anther wall consists of 4 layers- epidermis, endothecium, middle layer and tapetum. The main function of the anther of a flower is to produce the pollen of flowering plants. By the time when the pollen grain walls are at the maturity level, the tapetum layer disappears and the persisting middle wall layer flattens. At the maturity time of pollen grains only the epidermis and endothecium remain.
