1. Asexual Reproduction
Biology 4.1

2. Asexual Reproduction
Asexual reproduction results in the production of a new organism
The organism produced has ____________to the parent
Asexual Reproduction can be found in ____________

3. Binary Fission
Organisms that are prokaryotic ____________ like bacteria reproduce with ____________
The parent cell divides so that the daughter cell contains a single chromosome
____________

4. Binary Fission

5. Mitotic Protista are single cell eukaryotic ____________ organisms
Identical to the division of any cell with a nucleus
Follows the 4 steps: prophase, metaphase, anaphase, and
telophase

6. Mitotic

7. Fragmentation Fungi (mold and mushrooms) reproduce by ____________
The organism grows by sending thin string called ____________
Hyphae grow ____________ searching for food
____________

8. Animals Invertebrates ____________ are able to reproduce asexually
Some use division and re-growth ____________
Others use budding where ____________

9. Animals

10. Plants
Different plants will reproduce asexually with “runners” or complex root systems
Plants have a specialized structure that allows them to grow, called a ____________

11. Plants

12. What do you think?
In your groups think of 2 advantages and 2 disadvantages of asexual reproduction

13. Advantages to Asexual Reproduction
New organism is ____________
Do not need to find a partner
Low parent to offspring care, so ____________
The offspring is usually ____________

14. Disadvantages to Asexual Reproduction
Not a lot of genetic variety… ____________
Difficult for organism to adapt to ____________
Low parent-to-offspring care, ____________

15. Activity Each group will pull a type of organism at random
The group will then use the modeling clay to create 3D models
The models must demonstrate the asexual reproduction of that species
Groups will be given the opportunity to go on walk-about to see the models done by other groups
Students are encourage to ask questions about the models

16. Practice Questions
What is binary fission? How is it different form mitotic cell division?
How can fungi reproduce asexually?
How can an animal reproduce by budding?
What is an advantage to asexual reproduction?

17. Practice Questions
One arm of a sea star (with part of the central disk) can regrow a complete sea star. Sea stars often eat oysters, by attaching themselves to the outside of the oyster shell. Oyster farmers used to try to destroy the sea stars by cutting them in to pieces, and throwing them back into the ocean. What do you think was the outcome of this situation.
