Answer
(a) Difference between Egg and Sperms
| Egg | Sperms |
|---|---|
| Egg is stationary. | Sperm is capable of performing locomotion. |
| Egg has no locomotory organ. | Sperm has a special locomotory organ, the tail. |
| Released one at a time. | Released in millions. |
| The female gamete. | The male gamete. |
(b) Difference between Sexual Reproduction and Asexual reproduction
| Sexual Reproduction | Asexual Reproduction |
|---|---|
| In Sexual Reproduction male and female gametes are involved and fertilised. | In Asexual Reproduction male and female gametes are not involved. |
| Two organisms or parents are involved to produce an organism. | A single parent divides itself to two or more number of daughter cells. |
| This type of reproduction can be seen in higher level organisms. | This type of reproduction can be seen in lower level organisms. |
| E.g: Humans | E.g: Amoeba |
(c) Difference between Budding and Regeneration
| Budding | Regeneration |
|---|---|
| Budding is a process in which buds grow on the outside of the parents body. The buds detach themselves once they are capable of independent existence. | Regeneration is the process of generating lost parts of the body. It is also happens for reproductive purposes. Some organisms, when cut into multiple pieces then each piece develops into a young organism itself. |
| Budding is exclusively for reproduction. | Regeneration is for regrowth of lost body and in some cases also for reproduction. |
