Question:

Placentation, in which ovules develop on the inner wall of the ovary or in peripheral part, is:

Options:

1. Free central
2. basal
3. Axile
4. Parietal

Solution:

Placentation, in which ovules develop on the inner wall of the ovary or in the peripheral part, is called parietal placentation. In parietal placentation, the ovules are attached to the inner walls of the ovary, either on a single line or in a cluster. Free central placentation is when ovules are attached to a central column in the ovary, and basal placentation is when ovules are attached at the base of the ovary. Axile placentation is when ovules are attached to the central axis or column of a multi-chambered ovary. Parietal placentation is a common type of placentation found in many plants, including some fruits and vegetables.
