Double fertilisation is the characteristic feature of angiosperms. In this type of fertilisation one male gamete fuses with an egg and forms zygote. The second male gamete fuses with diploid secondary nucleus of central cell to form a triploidy primary endosperm nucleus.
reduction division occurs in the megaspore mother cells
(D)
a small central cell is present in the embryo
