What is the fate of the male gametes discharged in the synergid ?

Options

A. One fuses with the egg and other fuses with central cell nuclei
B. One fuses with the egg, other(s) degenerate(s) in the synergid
C. All fuse with the egg
D. One fuses with the egg, other(s) fuse(s) with synergid nucleus

Answer

A

Explanation

In flowering plants, out of the two male gametes discharged in synergids, one fuses with the egg and other fuses with the secondary or definitive nucleus present in central cell.
Egg (n) + 1st male gamete (n) `rarr` → Zygote (2n) `underset("(central cell nuclei)")underset("(2n)")("Secondary nucleus")` + 2nd male gamete (n) `rarr` PEN (3n)
