Question

The layer of anther wall, which help in its dehiscence is _________

• A. epidermis
• B. endothecium
• C. tapetum
• D. middle layers

Hint:

Fibrous thickenings in endothecium are crucial for pollen release.

Answer 1

The Correct Option is B

Step 1: Understanding anther structure.
The anther wall consists of four layers: epidermis, endothecium, middle layers, and tapetum.

Step 2: Role of endothecium.
The endothecium develops fibrous thickenings that generate tension during drying, which leads to anther dehiscence.

Step 3: Eliminating other layers.
Epidermis provides protection.
Tapetum nourishes developing pollen grains.
Middle layers degenerate during development.

Step 4: Conclusion.
Therefore, the endothecium is responsible for anther dehiscence.
