  • What is Reproduction?Reproduction is the process in which organisms produce more of their own kind.

    Asexual reproduction occurs when a new organism is produced by one parent. The new organism will be identical to the parent.

    Sexual Reproduction requires two parents each giving 23 chromosomes to the offspring.

  • Types of Asexual ReproductionParthenogenesisFissionVegetative PropagationFragmentationBudding

  • ParthenogenesisA female organism produces an egg that develops into a new organism without being fertilized.

    Identical copy of parent.

    Examples: insects, reptiles and fishes. Example

  • Whiptail LizardsParthenogenesis

    A female whiptail lizard may produce eggs that develop into identical versions of itself.

  • FissionA single-celled organism divides into two cells of the same size.

    Each is identical to the other.

    Examples: Bacteria, Paramecium, AmoebaExample

  • BacteriaFission

    A single-celled organism that has no nucleus or cell wall and reproduces by splitting in two.

  • Vegetative PropagationNew plants can be produced from sections of parent plants that are cut off.

    Identical copy of parent.

    Examples: spider plants, willow trees Example

  • StrawberriesVegetative Propagation

    Strawberries reproduce new plants by the division of cells from runners or roots.

  • FragmentationAn organism breaks up into fragments.

    Each of these fragments develops into an identical copy of the original organism.

    Examples: flatworm, planarian

    Example

  • Planarians Fragmentation

    The body of the parent breaks into pieces, each of which can produce an offspring

  • BuddingA bud grows on the body of the parent.

    Identical copy of its parent.

    Sometimes the bud separates from the parent and becomes independent. Examples: hydra, yeast, spongeExample

  • HydraBudding

    Cell division forms a bud that is an identical copy of its single parent that separates from the parent and becomes independent.
