The phenomenon of double fertilization involves the fusion of
- A.Two male gametes with one egg cell
- B.One male gamete with the egg and another with the secondary nucleus
- C.Two male gametes with two polar nuclei
- D.One male gamete with the synergid and another with the egg
Show correct answer & step-by-step solution
Correct answer: B — One male gamete with the egg and another with the secondary nucleus
Solution
- Syngamy involves the fusion of one male gamete with the egg cell to form a zygote.
- Triple fusion involves the fusion of the second male gamete with the two polar nuclei (or secondary nucleus) to form the primary endosperm nucleus.
- These two processes together constitute double fertilization.
- Hence the answer is (B).
