Binary fission How does it work?
The organism copies its DNA then splits in half
Example organisms: Bacteria Paramecium Amoeba
Budding How does it work? Outgrowth of cell
membrane pinches off and becomes its own organism
Example organisms: Hydra Yeast
Spores How does it work? Packets of genetic
information grow into new organism
Example organisms: Ferns Mosses Mold Mushrooms
Runners How does it work? New plant grows from horizontally growing stems
Example organisms: Strawberries Water lilies
Bulbs How does it work?
Underground nutrient-storage structure grows into new plant
Example organisms: Tulips Daffodils Onions
Regeneration How does it work?
Body parts re-grow or chunks grow into new organisms
Example organisms: Sea star Planaria Sponges Lobster
AKA “fragmentation”
All forms result in genetically identical offspring (unless mutation occurs)
Cell division by mitosis (only)
No need for Punnett squares for these organisms!
Common features
Divide sheet of paper into 4 equal sections Examine four different slides using microscope Provide overall title for activity List names of group members – on the front! In each box:
Draw diagram of specimen List name of specimen List magnification at which you viewed it (use your
best judgment regarding appropriate power) Label type of asexual reproduction the organism
undergoes
