Question

Define apomixis.

Answer 1

A few flowering plants such as some species of Asteraceae and grasses, have evolved especial mechanism, to produce seeds without fertilisation, called apomixis.
Apomixis is a form of asexual reproduction that mimics sexual reproduction. There are several ways of development of apomictic seeds. In some species, the diploid egg cell is formed without reduction division and develops into the embryo without fertilisation.
