Question

In a syncarpous unilocular ovary, ovules develop from two opposite lines on the wall. The placentation is

• A. Superficial
• B. Marginal
• C. Axile
• D. Parietal

Answer 1

The correct option is D Parietal

Parietal placentation develops in the syncarpous unilocular ovary from the two opposite lines of the wall due to which the ovary becomes falsely bilocular. The false septum is called replum.

A. Superficial placentation- the ovules develop over the entire inner surface of the ovary.

B. Marginal Placentation- the ovules develop on the ridge formed by the placenta over the ventral suture.

C. Axile Placentation- the ovules develop on the central axis which represents the wall where carpels have fused.

D. Parietal placentation- the ovules develop on two opposite lines of the wall of the ovary.

Hence, the correct answer is 'Parietal'.
