Cell Structures and Functions

1. Webquest Cell Structures and Functions Sarah L. Wood EDCI 5314 Introduction Task Process Evaluation Conclusion Teacher Page

2. Introduction: What is a cell, anyway? Every living thing is made up of cells. In fact, the cell is the smallest unit of life! Cells allow you to perform basic functions like eating, moving, breathing, and much more. You can only see them with the aid of a microscope, but even though they’re small, they’re very complex! Each part of a cell performs a job and cooperates with other parts to make the cell work. That’s why it’s so important to understand what each of these parts are and what they do. Let’s take a look!

3. Task: Worksheet, Diagrams, and Building My Own! In this activity, you will * complete a provided worksheet about cell part functions * label parts of an animal, plant, and prokaryotic cell * build your own cell using play dough, food, Microsoft Paint or any other approved medium Introduction Task Process Evaluation Conclusion Teacher Page

4. Process: Using the Internet to Guide Your TaskPage One 1.) The animal cell is a eukaryotic cell. Use the following link to tour an animal cell. Explore the following cell parts: nucleolus, nucleus, smooth endoplasmic reticulum, lysosome, mitochondrion, plasma membrane (or cell membrane), golgi body (or golgi apparatus), ribosome, and rough endoplasmic reticulum. Label these on your diagram and fill in the appropriate boxes on your worksheet. Remember to label your diagram as an animal cell and tell whether it is a eukaryote or prokaryote cell.

5. Process: Using the Internet to Guide Your TaskPage Two 2.) The plant cell is a eukaryotic cell. Use the following link to tour a plant cell. Explore the following cell parts: nucleus, golgi body, nucleolus, rough endoplasmic reticulum, smooth endoplasmic reticulum, vacuole, chloroplast, cell wall, mitochondrion, cell membrane, and cytoplasm. Label these on your diagram and fill in the appropriate boxes on your worksheet. Remember to label your diagram as a plant cell and tell whether it is a eukaryote or prokaryote cell. (Hint: cell part functions can be found by scrolling down to the blue words) Plant Cell Plant Cell Site Process Main Slide

6. Process: Using the Internet to Guide Your TaskPage Three 3.) Bacteria are one-celled organisms. A bacterium is an example of a prokaryotic cell. Use the following link to tour a bacterium. Explore the following cell parts: cilia, ribosome, DNA, cell membrane, cytoplasm, and flagella. Label these on your diagram and fill in the appropriate boxes on your worksheet. Remember to label your diagram as a bacterium and tell whether it is a eukaryote or prokaryote cell. Prokaryotic Cell Prokaryotic Cell Site Process Main Slide

7. Process: Using the Internet to Guide Your TaskPage Four Feel free to use the following links if you need additional help. Remember there are often several good sites to help you on the internet, but some cannot be trusted. All of the ones listed here have accurate information and can be trusted. http://www.cellsalive.com/cells/cell_model.htm http://personal.tmlp.com/Jimr57/tour/cell/cell.htm http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/A/AnimalCells.html http://sun.menloschool.org/~cweaver/cells/ Process Main Slide

8. Process: Using the Internet to Guide Your TaskPage Five 3.) Now that you have completed your worksheet and diagrams and understand cell structures and functions, you can begin building your own cell! You must build either an animal or plant cell. You are expected to include nine cell parts that apply to your cell. Use the websites below for help on building your cell. Supplies are available in the backroom.

9. Evaluation: Determining Your Grade The Webquest is worth 200 points total. (The same as two test grades.) * There are 26 total structures to label on the three diagrams. Each correctly named structure is worth two points. (52 pts.) * One point is given for giving each diagram a correct title. (3 pts.) * There are 15 cell parts on the worksheet. Every correct function of these parts is worth two points. (30 pts.) * One point will be given for every part that is correctly identified as belonging to animal, plant, and/or prokaryotic cell. (15 pts.) * Ten points will be given for writing your name on the worksheet, diagrams, and constructed cell. (10 pts.) * When constructing your own, 10 points will be given for every cell part that correctly resembles its actual structure and belongs to the cell you chose. (90 pts.)

10. Conclusion: Sending a “Thank you” It’s hard to think that something so small could make such a big difference! Cells truly are the building blocks of life. Now that you understand the structures and functions of each cell part I hope you will think about what has to be done for us to perform basic tasks! Thank you ribosomes, thank you nucleolus, thank you rough endoplasmic reticulum, thank you golgi apparatus… A BIG “thank you” goes to Mrs. Kelly Walbush for her excellent webquest from which I modeled my own. Her Webquest can be found here. Introduction Task Process Evaluation Conclusion Teacher Page

11. Teacher Page This Webquest was designed for a seventh grade life sciences class by Sarah L. Wood. Virginia Standards of Learning Addressed in this Webquest are as follows. LS. 1 The student will plan and conduct investigations in which d.) models are constructed to illustrate phenomena LS. 2 The student will investigate and understand that all living things are composed of cells. Key concepts include a.) cell structure and organelles (cell membrane, cell wall, cytoplasm, vacuole, mitochondrion, endoplasmic reticulum, nucleus, and chloroplast) b.) similarities and differences between plant and animal cells Please contact me at littlew00d@yahoo.com for additional information such as worksheets and diagrams used in this webquest.
