Question:
What is the fate of the male gametes discharged in the synergid?
All fuse with the egg
One fuses with the egg and other fuses with central cell nuclei
One fuses with egg other(s) degenerate(s) in the synergid
One fuses with the egg, other(s) fuse(s) with synergid nucleus
Solution:
Correct option is D. One fuses with the egg and other fuses with central cell nuclei. 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) → Zygote(2n) Secondary nucleus(2n) (central cell nuclei) + 2nd male gamete(n) → PEN(3n). So, the correct answer is 'One fuses with the egg and other fuses with central cell nuclei'
