What is the fate of the male gametes discharged in the synergid?
1 One fuses with egg other(s) degenerate (s) in the synergid.
2 All fuse with the egg.
3 One fuses with the egg, other(s) fuse(s) with synergid nucleus.
4 One fuses with the egg and other fuses with central cell nuclei.

Sperm and egg nuclei fuse due to
1 Base pairing of their DNA and RNA
2 Attraction of their protoplasts
3 Formation of hydrogen bonds
4 Mutual attraction
Explanation:
Sperm and male gamete fuses with egg or female gamete because of the attraction of their protoplast. Some chemicals are secreted by ovule or egg wall to attract the male gamete or sperm.

In the post fertilization changes within the ovule, the egg forms the ___________ While the fertilized fusion nucleus (product of triple fusion) develops the ____________ Respectively
1 Endosperm, embryo
2 Embryo, endosperm
3 Nucellus, embryo
4 Embryo, nucellus
