Development of Fruits

 The ovary of a flower develops into a fruit.

The walls of the ovary transform into the walls of the fruit (pericarp).

Fruits may be fleshy, as in mango and orange, or can be dry, as in groundnut and mustard.

In some plants, floral parts other than the ovary take part in fruit formation, as in apple and strawberry.

In these, the thalamus contributes to fruit formation. Such fruits are called false fruits.

Fruits that develop from the ovary are called true fruits.

Some fruits develop without fertilisation, and are known as parthenocarpic fruits (example: banana).
