Question:

What type of placentation is seen in sweet pea?

Options:

1. Basal
2. Axile
3. Free central
4. Marginal

Solution:

In sweet pea (Pisum sativum), the placentation is marginal, in which, the placenta develops along the junction of two carpels, in a unilocular ovary. In basal placentation, the ovules are few or reduced to one and are borne at the base of ovary e.g., compositae. In axile placentation, margins of carpels fold inwards, fusing together in centre of ovary to form a single central placenta. Ovary is divided into as many locules, as there are carpels e.g., Hibiscus, Asphodelus. Free-central placentation possesses a placenta arises as a central upgrowth from ovary base e.g., Stellaria.
