Question

Difference between axile and parietal placentation

Answer 1

Answer:

Placentation:

Placentation refers to the arrangement of ovules inside the ovary. It is of five basic types.

✓Parietal placentation

• When the ovules develop on the inner walls of the ovary, the ovary is said to have parietal placentation.

✓ Axile placentation

• In axile placentation, the placenta is axial and ovules are attached to it.

• Examples include China rose, lemon, and tomato.

Answer 2

Answer:

When the ovary is divided into two or more locules by septa, the placentation is axile. The inner angle created by the septa is where the ovules are connected along the central axis.

Additionally, there is no septum during parietal placentation, resulting in a unilocular ovary. The inner surface of the ovary walls is where the ovules are carried (or extensions of the walls).
