How can you differentiate between free central and axile placentation?

(N/A) $\rightarrow$ Placentation: The arrangement of ovules within the ovary is known as placentation. The placenta is a specialized tissue. Various types of placentation are observed in plants, including free central and axile placentation.
$\rightarrow$ The differences between them are as follows:

Free central placentation	Axile placentation
$(1)$ The ovary is unilocular (single chambered).	$(1)$ The ovary is multilocular (many chambers).
$(2)$ Ovules are borne on a central axis, and septa (membranes) are absent.	$(2)$ The placenta is axial, and ovules are attached to it in a multilocular ovary with septa.
