What is the function of tapetum in anther ?

Provide nutrition.

The correct answer is Option (3) – Provide nutrition.

The main function of the tapetum in the anther is to provide nutrition to the developing pollen grains. The function of the tapetum in an anther is to provide nutrition to the developing pollen grains. The tapetum is the innermost layer of the anther's wall and is responsible for nourishing the developing pollen cells. It has a dense cytoplasm and often contains multiple nuclei. The tapetum supplies essential nutrients, proteins, and enzymes to support the development and maturation of the pollen grains. This nourishment is crucial for the pollen grains to reach maturity and be capable of successful fertilization.

The tapetum does not help in dehiscence, protection, or fertilization. Dehiscence is the process by which the anther opens and releases the pollen grains. This is usually caused by the drying out of the anther wall. The tapetum does not play a role in this process.

The tapetum also does not provide protection to the developing pollen grains. The tapetum does not contribute to this protection.
