Axile placentation: In a multicarpellary syncarpous gynoecium the fusing margins grow inwards to meet in the center of the ovary to form an axis thus making the ovary multilocular. The ovules are borne on the central axis. e.g., Family Solanaceae and Liliaceae.

In marginal placentation the placenta forms a ridge along the______ suture of the ovary
1 Ventral
2 Marginal
3 Basal
4 Dorsal
Explanation:
In marginal placentation the placenta forms a ridge along the ventral suture of the ovary and the ovules are borne on this ridge forming two rows, as in pea

Statement A : When the ovules are borne on central axis and septa are absent, the placentation is axile. Statement B : In basal placentation, the placenta develops at the base of ovary and a single ovule is attached to it, as in sunflower, marigold.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Statement A is incorrect. When the ovules are borne on central axis and septa are absent, as in Dianthus and Primrose the placentation is called free central.
