Describe the parts of a fruit with a diagram.

(N/A) $\rightarrow$ The fruit is a mature or ripened ovary, developed after fertilisation. If a fruit is formed without fertilisation of the ovary, it is called a parthenocarpic fruit.
$\rightarrow$ Generally, the fruit consists of a wall or pericarp and seeds. The seed is enclosed by the pericarp in a fruit.
$\rightarrow$ The pericarp may be dry or fleshy. When the pericarp is thick and fleshy, it is differentiated into the outer epicarp, the middle mesocarp, and the inner endocarp.
$\rightarrow$ Drupe: In mango and coconut, the fruit is known as a drupe. They develop from monocarpellary superior ovaries and are one-seeded.
$\rightarrow$ In mango, the pericarp is well-differentiated into an outer thin epicarp, a middle fleshy edible mesocarp, and an inner stony hard endocarp.
$\rightarrow$ In coconut, which is also a drupe, the mesocarp is fibrous.
