Question

Fruits with fleshy epicarp, mesocarp, and endocarp are
A. Pome
B. Berries
C. Drupes
D. Syconus

Answer 1

Hint:- The fruit is one of the most important parts of the plant. It is the mature form of the ovary that presents in a flower. It contains seeds which previously remain as the ovule in the flower. A flower converts into fruit after its successful fertilization.

Complete step-by-step solution :
When the fertilization of a flower takes place by the pollen grain, the ovule which remains stored within the ovary, it grows into the seeds and the ovary converts into the fruit. So, fruit is a matured ovary of the flower formed after successful fertilisation of the gynoecium and it protects the internal seeds.
According to the anatomy of fruits, there are three main categories which are aggregate fruits, multiple fruits, and simple fruits. Aggregate fruits are produced from a single compound flower and it consists of many ovaries e.g. blackberries. Multiple fruits are produced from the fused ovaries e.g. pineapple. Simple fruits are produced from a single ovary and one or many seeds can be found in it and can be either fleshy or dry. In the case of fleshy fruit, the pericarp transforms the fleshy portion of the fruit. Examples of fleshy fruits are berries, pomes, and drupes.
Generally, the simple fruit consists of two parts that are the pericarp and the seed or seeds. The pericarp is a converted form of the outer wall of the ovary. It is further divided into three parts. First exocarp which is the outer layer of the pericarp. It builds the skin of the fruit. Next is the mesocarp which is the middle layer of the pericarp. The innermost layer of the pericarp is referred to as the endocarp. It is generally developed into the pith.
In poems the thought the mesocarp is fleshy, its exocarp is very papery or cartilaginous type. The thalamus is its fleshy part. In berries, the total pericarp is soft and fleshy and its seeds are scattered throughout the fruit. Other than its seeds, total fruit is edible.
Drupes are the fruit in which the exocarp is thin, the mesocarp is fleshy and the endocarp is hard and rigid. Syconus is a composite type of fruit in which the container of the flower becomes fleshy.
Therefore, the correct option is option B.

Note:- The fruit is the mature ovary of the flower and its seeds are the mature ovule found within the ovary. Generally, there are three types of fruit aggregate fruits, multiple fruits, and simple fruits. Simple fruit is two types, fleshy fruit and dry fruit. The pericarp and the seeds are the two parts of a fruit. Pericarp has three layers which are the exocarp, mesocarp, and endocarp. In the case of berries, the whole pericarp is fleshy.
