Question

What is meant by double fertilization?

• A. Fusion between egg and male gamete
• B. Fusion between secondary nucleus and male gamete
• C. Both (A) and (B)
• D. Formation of two zygotes

Answer 1

The correct option is C Both (A) and (B)

• Double fertilization is a complex fertilization mechanism of flowering plants.
• This process involves the joining of female gametophyte with two male gametes.
• In this case, syngamy between male and female gametes produces the embryo.
• At the same time, the secondary nuclei which are diploid in nature will fuse with another male gamete and forms the endosperm. It was first explained by Nawaschin.
  Hence, the correct option is C.
