Question

Which one is not a false fruit?
a. Apple
b. Mango
c. Strawberry
d. Cashewnut

Answer 1

Hint: False Fruit is the one that contains, in addition to a mature ovary and seeds, a significant amount of other tissue.

Complete answer:
True fruit is the fruit that is formed from the fertilized ovary of the flower and ovules get transformed into seeds. Mango develops from a ripened ovary and thus is called a true fruit. It is a kind of drupe. Hence, mango is not a false fruit

In apples, a major part of the fruit is formed from the thalamus, not from the ovary. That's the reason why it is called a false fruit. When the fruit is formed from secondary floral parts other than ovary they are called false fruits. In some fruits like apple, cashew the thalamus also contributes to fruit formation, hence it is a false fruit. In strawberry, the whole soft, edible part of which is represented by an overgrown receptacle. Hence, it is a false fruit.

Note: Development of fruits without fertilization is termed as parthenocarpy. Parthenocarpy is the natural or artificially induced production of fruit without fertilisation of ovules, which makes the fruit seedless. Examples include - Varieties of pineapple, banana, orange, grapes, etc.
