Structure of Tapetum
The tapetum is a single celled nutritive layer found behind the epidermis and endodermis. intially the cells are diploid but after several cell divisions they become polyploid. the cells are known as tapetal cells that have dense cytoplasm and a prominent nuclei. The cells are large because they provide nutrition for the developing pollen grains. Spherical cells called Pro-ubisch are present in the cells that help in the thickening of the exine.
In plants that engage in sexual reproduction involving two separate gametes- male and female, the tapetum aids this process by supporting the development of male gametes, especially pollen grains, within the anther.

The tapetum ensures that the pollen grains mature adequately, so as to obtain the reproductive success of flowering plants.
Tapetum – Types and Functions
The functions of tapetum entail the supply of nutrition and enzymes essential for the process of microsporogenesis and the successive development of pollen grains. This article discusses how the tapetum contributes significantly to the reproductive success of flowering plants, its types, and the functions it performs.
