Asexual Reproduction Unit 4-1 Notes Mr. Hefti – Pulaski Biology

2 Fill your chart in w/ the following information
Type of reproduction How does it work? Example(s) of organisms that reproduce this way Diagram Binary fission Budding Spores Eyes on tubers Runners Bulbs Regeneration Fill your chart in w/ the following information

3 Binary fission How does it work?
The organism copies its DNA then splits in half Example organisms: Bacteria Paramecium Amoeba

4 Budding How does it work?
Outgrowth of cell membrane pinches off and becomes its own organism Example organisms: Hydra Yeast

5 Spores How does it work? Example organisms:
Packets of genetic information grow into new organism Example organisms: Ferns Mosses Mold Mushrooms

6 Eyes on tubers How does it work? New plant grows out of the spud
Example organisms: Potatoes

7 Runners How does it work? Example organisms:
New plant grows from horizontally growing stems Example organisms: Strawberries Water lilies

8 Bulbs How does it work? Underground nutrient-storage structure grows into new plant Example organisms: Tulips Daffodils Onions

9 Regeneration How does it work?
Body parts re-grow or chunks grow into new organisms Example organisms: Sea star Planaria Sponges Lobster AKA “fragmentation”

10 Common features All forms result in genetically identical offspring (unless mutation occurs) Cell division by mitosis (only) No need for Punnett squares for these organisms!

11 Graded Assignment 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

12 Example(s) of organisms that reproduce this way
