This document discusses regeneration and fertilization. Regeneration is the renewal and restoration of tissues, organs, organisms, and ecosystems after damage or disturbance. It can be complete, with new tissue matching the lost tissue, or incomplete. Fertilization is the process of biological reproduction initiated by the fusion of male and female gametes, or sex cells, forming a zygote and starting embryo development, which eventually leads to a new individual organism.
