Question

Ovules are borne in two rows on the ridge of ventral sutura in ______ condition.

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

Answer 1

The correct option is A Marginal

In the marginal placentation, the placenta forms the ridge along the ventral suture along which the wall of the ovary fuse. The ovules are attached on this ridge in two rows. For example, Leguminosae.

B. In parietal placentation, the ovules are borne on the peripheral fused margins. For example, Brassica.

C. In axile placentation, the ovules are borne on the central axis, for example, tomato.

D. In basal placentation, the ovule is present at the base of the ovary, for example, Asteraceae.

Hence, the correct answer is 'Marginal'.
