Answer

Function of Tapetum

Tapetum is a layer of cells found in the anthers of flowering plants. It is located between the sporogenous tissue and the anther wall. It has a significant role in the development of pollen grains and seed production.

Production of Pollen Grains

The tapetum plays a crucial role in the production of pollen grains. It is responsible for providing nutrients and other substances that are essential for the development of pollen grains. The tapetum cells contain enzymes that break down starch and other compounds into simple sugars that can be used by the developing pollen grains. The nutrients produced by the tapetum are transported to the developing pollen grains through the middle layer.

Protection of Pollen Grains

The tapetum also provides protection to the developing pollen grains. It forms a protective layer around the developing pollen grains that prevents them from being damaged by harmful external factors. The tapetum layer also helps in maintaining the moisture level around the developing pollen grains, which is essential for their growth and development.

Contribution to Seed Development

In addition to its role in the development of pollen grains, the tapetum also contributes to seed development. The tapetum provides nutrients and other substances that are essential for the growth and development of the female gametophyte. The tapetum also plays a key role in the formation of the seed coat, which protects the developing embryo from external damage.

Conclusion

In conclusion, the tapetum plays a crucial role in the development of pollen grains and seed production. It provides nutrients and other substances that are essential for the growth and development of pollen grains and the female gametophyte. The tapetum also protects the developing pollen grains and contributes to the formation of the seed coat.

Answer

The tapetum is a specialised layer of nutritive cells found within the anther, of flowering plants, where it is located between the sporangenous tissue and the anther wall. Tapetum is important for the nutrition and development of pollen grains, as well as a source of precursors for the pollen coat.
