- (A), (B), (C), (D).
- (D), (C), (A), (B).
- (B), (A), (D), (C).
- (C), (A), (D), (B).
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
A typical anther wall has four layers around the sporogenous tissue.
Step 2: Order
Outermost is the epidermis (C). Below it is the endothecium (A), with fibrous thickenings that help dehiscence. Next are the middle layers (D), which degenerate as the anther matures. Innermost is the tapetum (B), which nourishes the microspores.
Step 3: Sequence
From outside to inside the order is C, A, D, B.
Final Answer:
The correct order from outer to inner is (C), (A), (D), (B). \[ \boxed{\text{(D) }\text{(C), (A), (D), (B).}} \]
