Document Summary
Most obvious & unique characteristic of life. Production of new individual organisms (offspring) from living organisms (cid:894)(cid:862)parent(cid:863) or (cid:862)parents(cid:863)(cid:895) Ability to make more of their own. All the chemical & physical qualities of life, or those which characterize and define each life form are passed onto a new generation of cells & individuals living organisms can reproduce by asexual reproduction and/or sexual reproduction. Binary fission: one individual separates into 2 individuals of equal size: e. g. bacteria escherichia coli. Multiple fission: one individual separates into several individuals of equal size: e. g. protist- plasmodium (causative agent of malaria, (in unfavourable condition) not enough food, limited spaces, budding: New individual arises from an outgrowth of another: e. g. hydra. (cid:862)daughter(cid:863) individual is of a different size: fragmentation and regeneration: Parent breaks off into pieces, each piece gives rise to a new individual: e. g. echinoderm; and anabaena (blue-green alga, parthenogenesis.
