Question

Distinguish between free central and parietal placentation

Answer 1

When the ovules are borne on central axis and septa are absent, as in Dianthus and Primrose the placentation is called free central. When the placenta is axial and the ovules are attached to it in a multilocular ovary, the placentation is said to be axile, as in China rose, tomato and lemon.
