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.
