Question

A true fruit is the one in which the fleshy part of the fruit is derived from
(a)Thalamus
(b)Ovary
(c)Inflorescence axis
(d)Apocarpous gynoecium

Answer 1

Hint: It is the edible part of most of the fruits that include the pericarp and other accessory structures. The main function of this part involves the protection of seed from outer environments.

Complete Answer:
In a true fruit, the fleshy part of the fruit is derived from the ovary. The fleshy and juicy part of the fruit is edible. The outer layer of the fleshy fruits is known as pericarp. It is the tissue that develops from the ovary wall of the flower and it surrounds the seed to protect it from environments. The pericarp is made up of three different layers:
Epicarp: It is the outermost layer of the pericarp that forms the outer thick skin of the fruit. Epicarp is also called as flavedo in citrus fruits.
Mesocarp: This is the fleshy middle layer of the pericarp of a fruit. It is commonly present in between the epicarp and the endocarp. It is the most edible part of the fruit. In citrus fruit, the mesocarp is called albedo.
Endocarp: It is the inside layer of the endocarp that surrounds the seed. In citrus fruit, the endocarp is a membranous and most consumable part of the fruit. In nuts, it constitutes the stony part that surrounds the kernel of pecans, walnuts, etc.

So, the correct answer is ‘ovary’.

Note: -In berries and drupes, the pericarp forms the edible tissue around the seeds.
-Chromoplasts are plastids that are responsible for pigment synthesis and storage in specific photosynthetic eukaryotes.
