Answer 2

Answer:

The correct answer is option B. Secretory tapetum is the type of tapetum which provides nourishment to the developing microspore mother cell.

Explanation:

Secretory tapetum is also called glandular tapetum.

• It helps in the formation of the pollen wall.
• It transports nutrients to the inside of the anther as it surrounds the anther locule.
• It contributes to the development of Orbicules.
• It synthesizes callase enzymes for the separation of microspore tetrads and produces pollenkitt, and tryphine which bind pollen grain together assisting in effective pollination.
