4. Answer these analysis questions in complete sentences in your notes…
Are organisms which reproduce asexually generally
complex creatures or simple organisms?
If an organism could reproduce both sexually and
asexually, what advantage would this provide?

5. Now lets explore some man-made methods of asexual reproduction…
1- Plant cuttings:
A small section of the stem and a few leaves are cut from a mature plant, then inserted into soil and kept moist for several weeks. The stem will form roots and turn into a new plant. This new plant will be genetically identical to the mature plant.

6. Answer this analysis question in a complete sentence in your notes…
Why would someone want to use cuttings to grow plants?

7. Now lets explore some man-made methods of asexual reproduction…
1- Grafting:
A bud from a mature tree (often a fruit tree) is placed into a cut made into the trunk of a different species of tree which is fast- growing. This bud will grow into a branch on the root stock and will produce fruit quickly, sometimes within 1 year.

8. Answer this analysis question in a complete sentence in your notes…
If an apple bud was grafted onto the root stock of a cottonwood tree, would the next year’s leaves look like apple leaves, or cottonwood leaves, or a combination of both? Explain.

9. Now lets explore some man-made methods of asexual reproduction…
3- Cloning:
A skin cell is removed from the animal that is to be duplicated and the nucleus of that cell is removed and saved. An egg cell from a donor animal is extracted and the nucleus is removed and discarded. The skin cell nucleus is inserted into the egg cell and allowed to “re-boot.” A baby _____ will be born – identical to the original animal.

10. Now, let’s practice some asexual reproduction… clone a mouse
You will need a worksheet with mice on the front
colored pencils
scissors
glue

12. Is cloning an example of sexual reproduction or asexual
Analysis questions: Answer these in complete sentences in your notebook. Write well enough that you can use these answers as a resource during the final test.
Is cloning an example of sexual reproduction or asexual
reproduction? Explain.
2. What is a somatic cell?
3. What is the purpose of the Egg Cell Donor?
4. What is the major difference between a somatic cell and an egg cell?
5. What gender will the mouse pup be? Why?
6. How is this method of cloning different from embryo twinning?
7-15 Make an inference – write a 5-sentence paragraph explaining your
opinion of human cloning. Should we be able to clone ourselves to
replace our body parts when they wear out? Should we clone food
animals?

13. For some extra credit, explore the click and clone interactive on the learn.genetics site, and complete the clone-a-mouse worksheet.
