Vedclass · Answer

(B) Double fertilization is a unique characteristic feature of angiosperms (flowering plants).It involves two fusion events: $1$. Syngamy: One male gamete fuses with the egg cell to form a diploid zygote $(2n)$.$2$. Triple fusion: The second male gamete fuses with the two polar nuclei (or secondary nucleus) to form a triploid primary endosperm nucleus $(3n)$.This process ensures the development of an embryo and the formation of endosperm to provide nourishment.
