In the process of double fertilization, which of the following events is essential for the formation of the embryo and the endosperm?
- A.Syngamy involves one male gamete and the egg cell, while triple fusion involves two male gametes and the central cell.
- B.Syngamy involves one male gamete and the egg cell, while triple fusion involves one male gamete and two polar nuclei.
- C.Syngamy involves two male gametes and the egg cell, while triple fusion involves one male gamete and the central cell.
- D.Syngamy involves one male gamete and the synergid, while triple fusion involves one male gamete and the egg cell.
Show correct answer & step-by-step solution
Correct answer: B — Syngamy involves one male gamete and the egg cell, while triple fusion involves one male gamete and two polar nuclei.
Solution
- Double fertilization is a unique feature of angiosperms.
- Syngamy is the fusion of one male gamete with the egg cell to form a diploid zygote.
- Triple fusion is the fusion of the second male gamete with two polar nuclei to form the primary endosperm nucleus.
- This process ensures the development of both the embryo and the nutritive endosperm.
- Hence the answer is (B).
