Question

Which part of the flower changes into fruit?
(a)Stamen
(b)Pistil
(c)Ovary
(d)Seed

Answer 1

Hint:A fruit is a seed-bearing part in flowering plants i.e. angiosperms formed after fertilization. The fruits play an important role in dispersal of seeds that is essential to the survival of the seedlings.

Complete answer:
A fruit develops from the maturation of one or more flowers, and the ovary of the flower forms all or part of the fruit. The ovules develop into seeds and the ovary wall, i.e. the pericarp, may become fleshy such as in berries or drupes, or form a hard-outer covering such as in nuts.

Additional information:
Fertilization encourages various changes in a flower: the anthers and stigma wilt, the petals fall off, and the sepals may be dropped or undergo changes; the ovary enlarges and forms fruits, and the ovules mature into seeds, each containing an embryo plant. The primary function of the fruit is the protection and propagation of the seed.
There are three overall means of fruit development:-
-Apocarpous fruits grow from a single flower having one or more distinct carpels. These are the simplest fruits. Example: Custard apple
-Syncarpous fruits grow from a single gynoecium having two or more carpels fused together. Example: Tomato
-Multiple fruits develop from many different flowers.
Many fruits are commercially important as human food, eaten in both forms i.e. fresh and preserved. Fruits are also used to make manufactured foods or drinks, such as fruit juices or alcoholic liquors. Olive fruit is compressed for olive oil. Spices like allspice, black pepper, paprika, and vanilla are acquired from different berries. Many dry fruits are used in decorations or in dried flower compositions. Many fruits provide natural dyes, a source of modern medicine, house decoration items, etc.

So, the correct answer is “ovary”.

Note:Fruits can be produced spontaneously in the absence of pollination and fertilization; such natural parthenocarpy results in seedless fruits such as bananas, oranges, grapes, and cucumbers. Such fruits are generally used for commercial purposes as it provides most products and is hassle-free.
