Question

explain development of seed without fertilization with suitable example
​

Answer 1

Answer:

Parthenocarpy is a phenomenon by which fruits are developed without the process of fertilization. The difference between the fruits developed naturally and through parthenocarpy is that the fruits formed through parthenocarpy are seedless. They are known as seedless or virgin fruits.

Example:

Seedless Grapes

Answer 2

Answer:

development of seed without fertilisation is called apomixis. In this case the unfertilised egg cell gives rise to embryo without fertilisation. In this case an embryo is formed directly from nucellus or integument tissue of ovule. It is a form of asexual reproduction that copies sexual reproduction.
