Identify the correct sequence of the anther wall layers from outer to inner in angiosperms.
(A). Endothecium
(B). Tapetum
(C). Epidermis
(D). Middle layer
Choose the correct answer from the options given below:
(A). Endothecium
(B). Tapetum
(C). Epidermis
(D). Middle layer
Choose the correct answer from the options given below:
Options
- A(A), (B), (C), (D).
- B(D), (C), (A), (B).
- C(B), (A), (D), (C).
- D(C), (A), (D), (B).
Correct answer
D. (C), (A), (D), (B).
Step-by-step solution
The anther wall in angiosperms is composed of four distinct layers.
From the outermost to the innermost, the sequence is:
1. Epidermis: The outermost protective layer.
2. Endothecium: Located just below the epidermis, it helps in the dehiscence of the anther.
3. Middle layers: One to three layers of cells that are ephemeral and lie between the endothecium and tapetum.
4. Tapetum: The innermost layer that nourishes the developing pollen grains.
Thus, the correct sequence from outer to inner is Epidermis (C), Endothecium (A), Middle layer (D), and Tapetum (B).
Answer: (C), (A), (D), (B).
From the outermost to the innermost, the sequence is:
1. Epidermis: The outermost protective layer.
2. Endothecium: Located just below the epidermis, it helps in the dehiscence of the anther.
3. Middle layers: One to three layers of cells that are ephemeral and lie between the endothecium and tapetum.
4. Tapetum: The innermost layer that nourishes the developing pollen grains.
Thus, the correct sequence from outer to inner is Epidermis (C), Endothecium (A), Middle layer (D), and Tapetum (B).
Answer: (C), (A), (D), (B).
