| The Fruit |
|
| |
| After fertilisation the ovary develops into the fruit and the ovules into seed. The ovary wall develops into the fruit wall called the pericarp. In some cultivated varieties of plants like bananas, grapes, apples etc., the ovary may develop into fruit without fertilisation. As a result of this ovules do not develop into seeds. Thus the fruits produced become seedless. Such fruits are called parthenocarpic fruits. The pericarp may be thick or thin. When it is thick it may show two or three layers the outer epicarp, the middle mesocarp and the inner endocarp. Sometimes the pericarp is not differentiated into three layers. |
| |
| Most species produce fruits known as true fruits, e.g., beans, orange, etc. But sometimes other floral parts like the thalamus or the calyx may grow and form a part of the fruit. Such a fruit is known as a false fruit, e.g., Apple. |
| |
| There are a large number of different kinds of fruits. They may be classified into three types, namely: |
| |
| 1. Simple fruits |
| |
| 2. Aggregate fruits |
| |
| 3. Multiple or Composite fruits. |
