→ (i) True fruits :
→ Develop only from the ovary.
→ In most plants, by the time the fruit develops from the ovary, other floral parts degenerate and fall off.
→ (ii) False fruits:
→ The thalamus also contributes to fruit formation.
→ Can be observed in a few species such as apple, strawberry, cashew, etc.→ (iii) 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. eg. Banana.
→ Banana is one such example.
→ Parthenocarpy can be induced through the application of growth hormones and such fruits are seedless.
