Explain the different types of placentation with example?

Explanation

(a) Marginal: It is with the placentae along the margin of a unicarpellate ovary. Example: Fabaceae.
(b) Axile: The placentae arises from the column in a compound ovary with septa.
Example: Hibiscus, tomato and lemon.
Superficial: Ovules arise from the surface of the septa. Example: Nymphaeceae.
Parietal: It is the placentae on the ovary walls or upon intruding partitions of a unilocular, compound ovary. Example: Mustard, argemone and cucumber.
(e) Free-central: It is with the placentae along the column in a compound ovary without septa.
Example: Caryophyllaceae, Dianthus and primrose.
(f) Basal: It is the placenta at the base of the ovary. Example: Sunflower (Asteraceae) Marigold.
