Solution: The various types of placentations found in flowering plants include:
- Marginal Placentation: Ovules are borne along the ridge formed by placenta along the ventral suture of ovary and form double rows. Examples include pea.
- Axile Placentation: Ovules are attached to an axial placenta in a multilocular fashion. Examples include lemon.
- Parietal Placentation: Ovules develop either along the inner wall or peripheral wall of the ovary. It originally has a single chamber but upon formation of false septum, it becomes double-chambered. Examples include mustard.
- Basal Placentation: A single ovule is attached to the placenta, which develops at the base of the ovary. Examples include marigold.
- Free Central Placentation: Ovules are borne on the central axis. Septa are absent. Examples include primrose.
