What is the difference between Axile and free central placentation?
When the placenta is axial and the ovules are attached to it in a multilocular ovary, the placentaion is said to be axile. Examples – china rose, tomato and lemon. When the ovules are borne on central axis and septa are absent, the placentation is called free central.
How can you differentiate between central and Axile placentation?
| Free central placentation | Axile placentation |
|---|---|
| There is only one chamber in the ovary. | The ovary is multicarpellary and septate. |
| Ovules are borne on the central axis. | The placenta arises from the centre, the septa fuse at the centre to form the central axis. Ovules are borne on the central axis. |
