Asexual SexualNumber of parent organisms

Compared to parent

Identical Combo of both parents

Complexity Simple, usually single-celled

Large, complex, multicellular

Example Bacteria Mammals

Asexual Reproduction• The process of making a new organism from a single parent organism.• Types:

• Mitosis- the process of a cell dividing into two identical daughter cells• Binary Fission- when a single celled organism divides into two new organisms• Budding- process of a new organism growing off the parent organism• Regeneration/Fragmentation- ability to repair and regrow severed body parts or

severed body parts develop and become independent organisms• Vegetative Propagation- stems grow underground and develop into new organisms• Sporulation- when an organism releases spores which develop and become

independent organisms

Type of Asexual Reproduction

Description Example

Binary Fission Prokaryote cell divides into two identical cells

Bacteria

Budding New organism grows off parent organism

Hydra

Regeneration Severed body parts can become new organisms

Starfish

Spore formation Seed like, parent organism releases spores which grow into new organisms

Dandelion

Vegetative Propagation New organism grows from roots of parent organism
