asexual reproduction

A type of reproduction in organisms that does not involve the union of male and female reproductive cells. Asexual reproduction occurs in several forms:
  • fission – the simple division of a single individual, as in bacteria or protozoa;

  • budding – growing out and eventual splitting off of a new individual, as in Hydra;

  • spore formation – as in fungi;

  • vegetative reproduction – in which a plant sends out runners that take root to forms new plants, as in strawberries, or new plants grow from organs such as bulbs.
