• A. In marginal placentation, placenta develops on the ventral side of an ovary
• B. Unlike marginal placentation where ovary is single chambered, in axile placentation ovary is multi-chambered
• C. Okra is an example of axial placentation i.e. ovary is multi-chambered and ovules are attached to the central axis
• D. Papaya is an example of basal placentation

Answer 1

Answer:

D. Papaya is an example of basal placentation

In marginal placentation, placenta develops on the ventral side of an ovary. Unlike marginal placentation where ovary is single chambered, in axile placentation ovary is multi-chambered. Okra (ladies finger) is an example of axial placentation i.e. ovary is multi-chambered and ovules are attached to the central axis. Papaya is an example of parietal placentation.
