Question

Tapetum present in the microsporangial wall occurs between

• A. Epidermis and endothecium
• B. Endothecium and middle layers
• C. Epidermis and middle layers
• D. Middle layers and sporogenous tissue

Answer 1

The correct option is D Middle layers and sporogenous tissue

Anther wall comprises of four layers: Epidermis, Endothecium, Middle layers and Tapetum. Epidermis is followed by a single layer of Endothecium, 2-3 middle layers and a single layer of Tapetum. Tapetum is the innermost layer of the anther wall. Tapetum surrounds the sporogenous tissue completely.

Therefore Tapetum is present between the middle layers and sporogenous tissue.

So, the correct answer is D.
