1. Drill 14 2/12/13 List 3 steps to binary fission.
What do bacteria form when they reproduce?

2. Drill 14 2/12/13 List 3 steps to binary fission.
DNA replicates and cell elongates
Cell wall and membrane began to divide
Cross walls form around DNA and cell divides.
What do bacteria form when they reproduce? Colonies

3. Objectives SWBAT describe 8 different types of asexual reproduction
SWBAT identify the phases of meiosis and recognize the differences between mitosis and meiosis.

4. Agenda
Asexual reproduction
Meiosis Notes

5. Asexual Reproduction

6. Division in Prokaryotes…
What characteristics of prokaryotes do you remember?
Watch the video clip and record any observations you make.
MAKE SURE THE SOUND IS ON.

7. Reproduction in Prokaryotes: Binary Fission
Division of one cell into two identical offspring cells

8. Asexual Reproduction in Animals…
Example 1 – Paramecium
Binary Fission
New organism is created by equal division of nuclear material and cytoplasm
Have the students watch the video clips and record their observations. NOTE: TURN OFF SOUND FOR THIS VIDEO. (Very annoying music.)

9. Asexual Reproduction in Animals…
Example 2 - Hydra
Budding
New organism develops from some generative point of the parent organism
Also seen in yeast cells

10. Asexual Reproduction in Animals…
Example 3 - Starfish
Regeneration
An entire new organism is produced from part of a parent organism or specific parts of an organism can be regenerated if lost

11. Asexual Reproduction in Plants…
Example 1 –
Coleus & Geraniums
Cuttings
New plant can develop from part of a leaf or stem from a parent plant

12. Asexual Reproduction in Plants…
Example 2 –
Tulips & Onions
Bulbs
New plant is produced from thick underground stem with leaves

13. Asexual Reproduction in Plants…
Example 3 - Potatoes
Tubers
New plant is produced from underground storage stem
Ask students, “Have you ever left a potato sit around too long? What started to happen?

14. Asexual Reproduction in Plants…
Example 4 - Strawberries
Runner
New plant arises from parent plant by forming a stem like structure that grows along the top of the ground

15. Asexual Reproduction in Plants…
Example 5 – Seedless Oranges & Jonagold Apples
Grafting
technique that attaches the stem from one plant to the stem and roots of another plant
Produces a hybrid plant that has characteristics of both plants

16. Practice Identifying Asexual Reproduction

17. Today’s Wrap-up…
Watch the video clip about planarian regeneration and respond to the following prompt:
What can scientists stand to learn from the regenerative properties of the planarian?
Only view the first 5 minutes of the video.
