Question

Identify the plant with multilocular ovary.
A. Cucumber
B. Cashew
C. China Rose
D. Chilli

Answer 1

Hint: Placentation: The position of ovules with respect to the ovary is known as placentation. The placentations are of different types namely or five types that are marginal, axile, parietal, basal, central and free central. The main function of placentation is the transfer of nutrients as placenta do in humans. It is also used in exchange of gases and also in removal of excretory wastes.

Complete answer:
Placenta is a specialized and disc shaped tissue, which essentially joins the ovules to the ovary by connecting embryos. Placentation in botany, is the term coined to define the way ovules and developing seeds are arranged, attached to the plant's ovary.
Cucumber :- parietal placentation, 'the ovules develop on the inner wall of the ovary and sometime on the peripheral part of the ovary. chambered due to the formation of the false septum. It is found in cucumber and mustard
Cashew :- it is a type of seed only and not a true fruit. So placentation can not be described for such a type of seeds. It is a type of false fruit. The cotyledon of cashew is edible and can be used to eat.
China rose :- it possesses axile placentation. 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.
Chilli :- it has free central placentation.

Our correct answer is C that is a china rose.

Note: The placentations are of different types namely.
Marginal placentation:- the placenta forms a ridge along the ventral suture of the ovary and the ovules are borne on this ridge forming two rows, as in ‘pea. The placenta helps to provide nourishment to the developing embryo. It expels out waste and undigested material from developing embryos.
