Question

Fusion of a male gamete with egg in embryo sac is

• A. Autogamy
• B. Syngamy
• C. Double fertilization
• D. Triple fusion

Answer 1

Answer: (B)

Syngamy

Syngamy and triple fusion are two events of sexual reproduction in plants. Syngamy is the fusion of one of the male gamete with the egg cell to produce a zygote while In triple fusion, second male gamete fuses with two polar nuclei to produce primary endosperm nucleus.

Since two types of fusions, syngamy and triple fusion take place in an embryo sac the phenomenon is termed double Fertilisation.

So, the correct answer is 'Syngamy'.
