Description:
Asexual reproduction is when one parent creates offspring without mating. Methods include division (like in bacteria), budding (seen in yeast), and regeneration (like in starfish). It makes identical or very similar offspring, causing quick population growth but less variety compared to mating.
Asexual reproduction has different methods. Binary fission divides a parent cell into two, seen in bacteria. Budding, like in yeast and Hydra, forms new individuals from parent projections. Fragmentation, seen in starfish, involves breaking and growing new parts. Vegetative propagation in plants like potatoes and strawberries creates new plants from roots or stems. Spore formation, as in fungi, produces specialized cells that grow into new organisms. Parthenogenesis, observed in some insects and reptiles, allows eggs to develop into offspring without fertilization.
