Q. With regard to the types of plantation in flowering plants, consider the following statements:

2. In parietal placentation, the ovules develop on the outer periphery of the ovary.
Which of the statement(s) given above is/are correct?

Morphology of Flowering Plants

Solution:

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. In parietal placentation, the ovules develop on the inner wall of the ovary or on peripheral part. Ovary is one-chambered but it becomes two chambered due to the formation of the false septum, e.g., mustard and Argemone
