Which one forms endosperm after fusion with male gamete ?
(A) Oosphere
(B) Synergids
(C) Antipodals
(D) Secondary nucleus
Key: D
Sol:
Sol:
Endosperm is formed from the primary endosperm nucleus. Its formation starts before the formation of embryo. Primary endosperm nucleus is produced by fusion of secondary nucleus and second male gamete. The endosperm is thus tripled (3n).
