  2. 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.

  3. Types of Asexual Reproduction • Parthenogenesis • Fission • Vegetative Propagation • Fragmentation • Budding

  4. 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.

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

  6. Fission • A single-celled organism divides into two cells of the same size. • Each is identical to the other

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

  8. 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.

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

  10. Fragmentation • An organism breaks up into fragments • Each of these fragments develops into an identical copy of the original organism

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

  12. 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.

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