What is the function of the tapetum in the microsporangium?

Nourishment of pollen grains

The correct answer is Option (2)-Nourishment of pollen grains

The function of the tapetum in the microsporangium is the nourishment of pollen grains.

The tapetum is the innermost layer of cells in the wall of the microsporangium. Its primary function is to provide nourishment and support to the developing pollen grains. The tapetum cells are rich in cytoplasm and contain various nutrients, including carbohydrates, proteins, and lipids.

During microsporogenesis, the tapetum supplies essential nutrients and metabolites to the developing pollen grains, promoting their growth and maturation. Cells of the tapetum possess dense cytoplasm and generally have more than one nucleus.
