Prokaryotes, Eukaryotes, and Endosymbiotic Theory
Process
Phase 1: Get the information!
First, let's split into groups of 4. There will be four members in your group and each person will be responsible for a particular reading. After the new information has been read, you will then be charged with teaching your peers. This is important! If you don't understand what you have read, how can you teach your group members? If you are having trouble, ask a peer for help or the teacher.
Now number yourselves: group member 1, group member 2, group member 3, and group member 4.
- Group Member 1: Please read the sections beneath: "The Origin and Evolution of the Cell" and "The First Cells" from http://www.ncbi.nlm.nih.gov/books/NBK9841/
- Group Member 2: Please read the sections beneath: "The Evolution of Metabolism" and "Present-Day Prokaryotes" from http://www.ncbi.nlm.nih.gov/books/NBK9841/
- Group Member 3: Please read the section beneath: "Eukaryotic Cells" from http://www.ncbi.nlm.nih.gov/books/NBK9841/
- Group Member 4: Please read the sections beneath: "The Development of Multicellular Organisms" from http://www.ncbi.nlm.nih.gov/books/NBK9841/
As you reading write yourself reminders of what's important from the reading. What can you teach your peers about your reading? This is very important as you will have group assignments to complete shortly. So make sure to teach your group well as it's important for you all to know the entire article!
Phase 2: Better think about it!
Venn Diagram (5 points)
Once you've completed the reading and you taught everyone about your section, fill out the Venn Diagram worksheet provided below. Fill out the Venn Diagram using the reading you did first, then if you need additional information you can use this video: https://www.youtube.com/watch?v=RQ-SMCmWB1s
Concept Definition Maps (4 points)
Now, move on to complete the Concept Definition Maps of prokaryotes and eukaryotes as a group using the notes from your reading and your completed Venn Diagram for help. Once all the groups have completed this assignment, we will discuss our answers as a class. We will compile of the information students provided so that we have a thorough and comprehensive understanding of prokaryotic and eukaryotic cells.
Group Discussion & Learning Log (6 points)
Last, we will get back into our groups and discuss the theory of endosymbiosis for 7 minutes.
- First, what is endosymbiosis?
- How did it happen?
- And what parts of the cell were involved?
Once the discussion time is completed, individually, you should take the next ten minutes to write a learning log in your lab notebook.
For the learning log answer the following question:
- Why was the evolution of prokaryotes to eukaryotes a significant event to the history of life?
- Use the information you gained from the previous exercises as supportive evidence to support your ideas.
Phase 3: Let's make something!
Prokaryotic & Eukaryotic Cell Models (60 points)
At this point, you should know all about prokaryotic and eukaryotic cells, how they differ, how they are the same, and how they came to be. I want you to use this new knowledge to create two models: a prokaryotic cell and a eukaryotic cell. You should be as creative as you can! You can work in pairs or as individuals, it is up to you as long as you contribute equally or wholly to the project.
Here are the rules:
- Two models must be made. One representing prokaryotic cells and the other eukaryotic cells. YOU MUST MAKE ONE OF EACH!
- The following parts of the cell must be included in your models:
Cytoplasm
DNA
Nucleoid region
Nucleus
Ribosomes
Cell wall
Golgi apparatus
Rough endoplasmic reticulum
Cilia
Flagella
**Remember both cells may not have all of these component parts!**
3. Your models can be 2-D or 3-D but can not be a drawing or coloring.
4. Your models can be computer generated, edible, physical, or anything else you can think of as long as the component parts of the cell are identified.
Teach Me: Endosymbiotic Theory (25 points)
Once your models are complete you must also provide some way to teach me about endosymbiotic theory. Like all of our Teach Me assignments, you must address me like I am your student and I have no clue what endosymbiosis is.
Here are the rules:
- You can teach me in any way that you want: verbal lesson, video, written report, board game, etc. Again, get creative here! I like to have fun when I learn new things!
- You must answer the following questions:
1. What is the Endosymbiotic Theory?
2. When do we think it occurred?
3. What types of cells or cell components did it involve?
4. How did this endosymbiosis lead to the evolution of eukaryotic cells?
