Question

What is syngamy in the context of double fertilisation?

Options

• Fusion of both male gametes together

• Degeneration of the synergid cell

• Fusion of the tube nucleus with polar nuclei

• Fusion of one male gamete with the egg cell to form a zygote (2n)

Answer 1

Syngamy is the fusion of one male gamete (sperm) with the egg cell, resulting in the formation of a diploid zygote (2n). This zygote subsequently develops into the embryo. Syngamy is one of the two fertilisation events that collectively constitute double fertilisation in angiosperms.
