What is reproduction

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.


Types of asexual reproduction

Types of Asexual Reproduction

  • Parthenogenesis

  • Fission

  • Vegetative Propagation

  • Fragmentation

  • Budding


Parthenogenesis

Parthenogenesis

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

  • The new organism is an exact copy of her.

  • Common examples occur in insects, reptiles and fishes.


Whiptail lizards

Whiptail Lizards

Parthenogenesis

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


Fission

Fission

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

  • Each is identical to the other


Bacteria

Bacteria

Fission

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


Vegetative propagation

Vegetative Propagation

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

  • New plants reproduced in this way are identical to the parent plant.

  • We see this in spider plants and willow trees, for example.


Strawberries

Strawberries

Vegetative Propagation

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


Fragmentation

Fragmentation

  • An organism breaks up into fragments

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


Planarians

Planarians

Fragmentation

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


Budding

Budding

  • A bud grows on the body of the parent

  • As the bud grows, it forms an identical copy of its parent

  • Sometimes the bud separates from the parent and becomes independent.


Hydra

Hydra

Budding

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