No. |
Double fertilisation |
Triple fusion |
Definition |
||
1. | A mechanism of fertilisation which occurs in the flowering plants where one sperm fertilizes the egg to form zygote and one sperm fuses with cell nuclei to form endosperm, this is called as double fertilisation. | A mechanism of fertilisation where one sperm nucleus fuses with two polar nuclei to form an endosperm, this is called as Triple fusion. |
Process |
||
2. | The process of fertilization of angiosperms mainly occurs. | The fertilization process of two polar nuclei occurs in the embryo sac. |
Formation |
||
3. | In the double fertilization, formation of diploid zygote takes place. | In the triple fusion, formation of endosperm takes place. |
Involved number of sperms |
||
4. | Two sperms are involved in the double fertilization. | Only one sperm is involved in the triple fusion. |
Result |
||
5. | Result shows both primary endosperm nucleus and a zygote. | Result shows primary endosperm nucleus. |
Produces |
||
6. | Both triploid endosperm and diploid zygote are produced. | Only triploid endosperm is produced. |
