How do Organisms Reproduce – Notes
Reproduction and its Significance
Reproduction is the process by which an organism gives birth to a new individual.
DNA variation is useful for the survival of a species, during drastic changes in their environment.
DNA variations are passed to the subsequent generations when they reproduce.
Reproduction in Unicellular and Multicellular Organisms
Organisms like Hydra reproduce by budding. They use the regenerative cells for reproduction in the process of budding. A bud develops as an outgrowth due to repeated cell division at a specific site on the hydra. Each of these buds develops into a new individual.
