Embryo sacs of some apomictic species appear normal but contain diploid cells. Suggest a suitable explanation for the condition.

- Apomixis is development of a seeds without prior fertilization. Example: replacement of the flower by bulbils and replacement of seed by a plant.

- It is observed in few flowering.

- Apomixis is a form of asexual reproduction that mimics sexual reproduction.

- Apomixis avoids the processes of meiosis and fertilization, leading to embryo development.

- The offsprings produced in this case are genetically identical to the parent plant.

- Embryo sacs of some apomictic species appear normal but contain diploid cells due to absence of meiotic division at the megaspore mother cell stage.

- As the megaspore mother cell has a diploid nucleus, if it undergoes mitosis instead of meiotic, all the resulting nuclei and cells will be diploid in nature.

- Apomixis is common in plants like Asteraceae, Poaceae.
