उत्तर
The phenomenon observed in some plants wherein parts of the sexual apparatus are used for forming embryos without fertilization is called apomixis.
Explanation:
Apomixis is when parts of the sexual apparatus in some plants make embryos without fertilization. This means that sexual reproduction is replaced by an asexual process. This allows embryo development without meiosis or syngamy, preserving desirable traits in plants indefinitely. It is observed in some species of Asteraceae and grasses and is important in horticulture and agriculture for maintaining hybrid vigor.
