Detailed explanation-1: -Abstract. In flowering plants, two male gametes from a single pollen grain fuse with two female gametes, the egg and central cells, to form the embryo and endosperm, respectively.
Detailed explanation-2: -Male gamete in plant is called pollen grain that contains two sperm nuclei and female gamete is called ovule that contains egg cell and two polar nuclei.
Detailed explanation-3: -In flowering plants, the female gametophyte is produced inside the ovule within the ovary of the flower. When mature, the haploid gametophyte produces female gametes which are ready for fertilization. The male gametophyte is produced inside a pollen grain within the anther.
Detailed explanation-4: -The male gamete present in pollen grain moves into ovules and fuses with female egg cell inside ovules and zygote is formed. This process is called fertilization.
