1AnswerA·
Concept: This question tests your knowledge of placentation, which is the arrangement of ovules within the ovary of a flower.
Why (A) is correct: In axile placentation, the ovary is multilocular (divided into several chambers or locules), and the ovules are borne on a central axis. This is characteristic of plants like tomato, lemon, China rose, and orange. The placenta forms a central column, and the ovules are attached to it in each locule.
Why other options are wrong:
- (B) Parietal: Ovules develop on the inner wall of the ovary or on peripheral part. The ovary is one-chambered but becomes two-chambered due to the formation of a false septum (e.g., mustard, Argemone).
- (C) Free central: Ovules are borne on a central axis, and the ovary is unilocular (single-chambered) without septa (e.g., Dianthus, Primrose).
- (D) Marginal: The placenta forms a ridge along the ventral suture of the ovary, and the ovules are borne on this ridge, typically in two rows (e.g., pea).
NEET Tip: Remember common examples for each type of placentation. For axile, think of 'TLC' - Tomato, Lemon, China rose.
Correct Answer: (A)
Axile
