Solution:

In marginal placentation, the ovules are attached to the placenta in a single row along the ventral suture of the ovary. In axile placentation, the ovules are attached to the central axis in a multilocular ovary. In parietal placentation, the ovules develop on the inner wall of the ovary or on peripheral part. In free central placentation, the ovules are borne on central axis and septa are absent. In basal placentation, the placenta develops at the base of ovary and a single ovule is attached to it.
