Q. When ovules at two points are developed, from the inner wall of the unilocular ovary, the placentation is called

AIIMSAIIMS 1996

Solution:

In parietal placentation, two or more longitudinal placentae develop along the wall of a syncarpous or compound pistil. The ovary is usually unilocular. In marginal placentation,a single longitudinal placenta having one or two alternate rows of ovules occur along the wall of the ovary, called ventral suture. In superficial placentation, the ovules develop on the whole inner surface of the ovary including the septa, if present. In basal placentation, the pistil can be monocarpellary or syncarpous. The ovary is unilocular. It bears a single placenta at the base with generally a single ovule.
