A fruit is a seed-bearing structure that develops from the ovary of a flowering plant post-fertilisation in sexually reproducing plants. After the process of fertilisation, usually all the parts of a flower wither away, except for the ovary and the ovules which mature into the fruits and the seeds, respectively. The fruits' main purpose is not merely to nourish you or please your palate. Yes! The main purpose of a fruit is to protect the seeds they enclose. In fact, in certain plants fruits can be inedible, unappealing or too little to be used as food. However, some fruit varieties such as bananas and grapes may not have seeds. These fruits are parthenocarpic, or seedless fruits. Fruits of different plants can vary in shapes, colours, taste, texture, nutritional value and even in longevity. Now let's take a closer look at the various parts of a fruit.
Fruit has two parts, pericarp and the seed. Seed is the developed ovule. Pericarp is the ripened ovary wall. This pericarp could be thin and delicate, thin and rigid, or thick and meaty. Pericarp (fruit wall) is differentiated into 3 layers:
However, the ovarian wall does not always develop into a juicy, delicious fruit like that in a peach or a mango. For instance, it turns into a dry, brittle protective pod in kidney beans.
