Which function of tapetum is correct ?a)Helps in pollen wall formation...
Tapetum secretes Ubisch bodies which get covered with sporopollenin and so increase thickness of exine of pollen grain wall. Tapetum provides nourishment to developing microspores. It also secretes callase enzyme which dissolves callose substances by which four pollens of a pollen tetrad are united, hence separating microspores or pollens of a tetrad.

Which function of tapetum is correct ?a)Helps in pollen wall formation...
Function of Tapetum:
Tapetum is a specialized layer of cells found in the anther of flowering plants. It plays several important roles in the development and maturation of pollen grains.
Helps in pollen wall formation:
- Tapetum is involved in the synthesis and deposition of materials that form the exine (outer layer) of the pollen wall. It provides structural support and protection to the developing pollen grain.
Transportation of nutrients to inner side of anther:
- Tapetum cells are responsible for providing essential nutrients and other substances to the developing pollen grains. They act as a source of nourishment, ensuring the proper growth and development of pollen.
Synthesis of callase enzyme for separation of microspore tetrads:
- Callase enzyme is produced by the tapetum cells and is essential for the separation of microspore tetrads (groups of four haploid cells). This process is crucial for the release of individual pollen grains from the anther.
Conclusion:
Tapetum plays a vital role in the development of pollen grains by supporting pollen wall formation, providing nutrients, and producing enzymes for the separation of microspore tetrads. All of these functions contribute to the successful maturation and release of pollen for fertilization in flowering plants.
