Reparative |
Restorative regeneration |
|
In reparative regeneration, the organism has the power only to repair certain damaged cells of the body. Liver has the extensive power of reparative regeneration. |
In restorative regeneration, the organism can redevelop the severed body parts or the whole body can be formed from a body segment. Regenerating of organs and body part such as limbs, tail, external gills. |
(ii)
|
Capacitation |
Fertilization |
|
Fertilization of the ovum occurs in the ampulla of the fallopian tube. On reaching the fallopian tube the spermatozoa undergo some changes, which are collectively known as sperm capacitation. |
The fusion of the male and the female gametes to form zygote is called fertilization. |
