Describe the various types of placentations found in flowering plants.

Placentation – Arrangement of ovule within the ovary is known as placentation. Various types of placentations found in flowering plants are

(1) Marginal placentation

The placenta forms a ridge along through the ventral suture of the ovary, ovules are borne on the ridge to form two rows.

Example: Lemon


(3) Parietal placentation

Ovules develop on the inner wall of the ovary or on the peripheral. It is single-chambered, but due to the formation of a false septum, it becomes two-chambered.

Example: Mustard


(4) Basal placentation

Placenta develops at the base of the ovary wherein a single ovule is attached to it.

Example: Marigold


(5) Free central placentation

Ovules are borne on the central axis and septa are absent
