9. Differentiate between the following:-
(iv) syngamy and triple fusion
The differences between syngamy and triple fusion are as follows:
Syngamy | Triple fusion |
It refers to the fusion of male gamete with female gamete i.e egg cell in angiosperms is called syngamy | It refers to the fusion of the second male gamete with the 2 polar nuclei of the central cell. Since, in this fusion, 2 polar nuclei and one sperm nuclei fuse, it is called triple fusion |
The end product is a zygote which is a diploid structure | The end product is the primary endosperm nuclei which are triploid. |
Both male and female gametes are involved within the syngamy. | Only male gametes participate in the triple fusion. |
