Question

Differentiate between syngamy and triple fusion.

Answer 1

Syngamy and triple fusion are two events ofsexual reproduction of plants. Syngamy is the fusion of male and female gametes to produce a zygote. In triple fusion, a third sperm nucleus fuses with the central cell in the embryo sac, producing the endosperm. The main differencebetween syngamy and triple fusion is thatsyngamy is a type of generative fertilization whereas triple fusion is a type of vegetative fertilization. Syngamy occurs in animals and fungi as well. But, triple fusion only occurs inangiosperms.

Answer 2

Answer:

* Syngamy ---->

• The fusion of the male and female gametes during fertilization is named syngamy.
• Syngamy is a generative fertilization.
• It produces a zygote which forms the embryo.
• The end product is diploid structure.
• Both male and female gametes are involved within the syngamy.
• Syngamy occurs in animals and plants.

*Triple fusion ----->

• The fusion of the sperm cell with the two polar nuclei during double fertilization is called triple fusion.
• Triple fusion is a vegetative fertilization.
• It produces endosperm cells that develop into the endosperm.
• The end product is a triploid structure.
• Male gametes are only involved in the triple fusion.
• Triple fusion occurs in angiosperms.

NOTE - The triploid nucleus serves as the primary endosperm nucleus, giving rise to the endosperm of the seed, which stores nutrients of the seed. It is often noted that syngamy is additionally mentioned as true fusion.
