Explain structure of fruit and give information about its types

Explanation

Pericarp: As ovules mature into seeds the ovary develops into a fruit, i..e, the transformation of ovules into seeds and ovary into fruit proceeds simultaneously. The wall of the ovary develops into the wall of fruit called pericarp.
Types of fruit: The fruits may be fleshy as in guava, orange, mango etc. or may be dry, as in groundnut and mustard etc. Many fruits have evolved mechanisms for dispersal of seeds.
False fruit: In most plants by the time the fruit develops from the ovary, other floral parts degenerate and fall of. However in a few species such as apples, strawberry, cashew etc. the thalamus also contributes to fruit formation. Such fruits are called false fruits.

True Fruit: Most fruits however develop only from the ovary and are called true fruits.
Parthenocarpic Fruits: Although in most of the species, fruits are the results of fertilisation, there are a few species in which fruits develop without fertilisation. Such fruits are called parthenocarpic fruits. Banana is one such example. Parthenocarpy can be induced through the application of growth hormones and such fruits are seedless.
