Question

Which one is not included under wall layers of anther?

• A. Epidermis
• B. Endothecium
• C. Pericycle
• D. Middle layers

Hint:

Think of root/stem anatomy versus anther anatomy.

Answer 1

The Correct Option is C

Step 1: A mature anther wall, from outside to inside, has four layers: epidermis, endothecium, middle layers, and tapetum.

Step 2: Epidermis is the outer protective layer, endothecium helps in dehiscence through fibrous thickenings, middle layers are a few compressed cell layers, and tapetum nourishes the developing pollen.

Step 3: Pericycle is a tissue found in roots and stems, lying between the vascular tissue and endodermis. It has no role in anther structure.

Step 4: So the layer not found in the anther wall is pericycle.
