(B) Thalamus also contributes to fruit formation in case of apple and cashew . Such fruits are called true  fruits .

(C) In  parthenocarpic fruits,  fruits develop without fertilisation .

(D) Parthenocarpy can't be induced through the application of growth hormones and such fruits are seedless.

(E) Banana is an example of false fruit  .

Choose the correct answer from the given options .

Options:

A,B and D  only 

B,D and E only .

A, D and E only 

D and E only .

Correct Answer:

B,D and E only .

Explanation:

The correct answer is (Option ) 2 -B,D and E only .

In most plants, by the time the fruit develops from the ovary, other floral parts degenerate and fall off.

However, in a few species such as apple, strawberry, cashew, etc., the thalamus also contributes to fruit formation. Such fruits are called false fruits .

Most fruits however develop only from the ovary and are called true 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.
