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 in flowering plants is defined as the asexual formation of a seed from the maternal tissues of the ovule, avoiding the processes of meiosis and fertilization leading to embryo development.

In some plants, normal sexual reproduction has no meiosis and syngamy. It is of two types- vegetative reproduction and agamospermy. In vegetative reproduction plants develop from parts other than seeds. In agamospermy, plants produce seeds as means of propagation by abnormal method.
