Sexual Reproduction In Flowering Plants

Question

Apomixis is

formation of seeds by fusion of gametes

formation of seeds without syngamy and meiosis

formation of seeds with syngamy but no meiosis

none of the above

Solution

formation of seeds without syngamy and meiosis

Apomixis (Gk. apo-without, mixismixing) is a mode of reproduction which does not involve formation of zygote through gametic fusion. It is, therefore, akin to asexual reproduction. In plants apomixis commonly mimics sexual reproduction but produces seeds without fertilisation, e.g., some species of Asteraceae and grasses.
