Is pollination and fertilisation necessary in apomixis? Give reasons.

Text Solution

Verified by Experts

No, they are not necessary. Apomixis is an alternative to sexual reproduction although the female sexual apparatus is used in the process. In apomicts, embryos can develop directly from the nucellus or synergid or egg. Therefore, there is no need for either pollination or fertilisation.
