REGENERATION AND FERTILIZATION

GROUP 4

REGENERATION

REGENERATION is the process of renewal, restoration, and growth that makes genomes, cells, organs, organisms and ecosystem resilient to natural fluctuations or events that cause disturbance or damage…

•Regeneration can either be complete where the new tissue is the same as the lost tissue, or incomplete where after the necrotic tissue comes fibrosis.

Splitting may be intentional or accident due to man-made or natural damage by the environment of predators.

FERTILIZATION

• An act or process of initiating biological reproduction by insemination or pollination…•The union of male and female gametes to form a zygote…

•The fusion of gametes to initiate the development of a new individual organism.•In animals, the process involves the fusion of an ovum with a sperm, which eventually leads to the development of an embryo. •Depending on the animal species, the process can occur within the body of the female in internal fertilization, or outside.
