what is double fertilisation and how it is beneficial for plant
Answers
Answer:
Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). ... Some plants may form polyploid nuclei. The large cell of the gametophyte will then develop into the endosperm, a nutrient-rich tissue which provides nourishment to the developing embryo
Double fertilization is a complex fertilization mechanism of flowering plants. This process involves the joining of a female gametophyte with two male gametes. It begins when a pollen grain adheres to the stigma of the carpel, the female reproductive structure of a flower.
The main advantage present in the double fertilization of angiosperms is energy conservation. The endosperm formed by fusion of the two polar nuclei and a sperm only begins to develop and store nutrients after it has been fertilized by a sperm cell.
