Cell Unit Expectations

By the end of the unit you should have the following completed:

1. Be able to define and give an example when appropriate of:

Group A: Cell Theory, Anton van Leeuwenhoek, prokaryotes, nucleus, eukaryote, organelles
Group B: Mitochondria, Plasma (cell) membrane, Golgi apparatus, Centrioles, Endoplasmic Reticulum, ribosome, lysosome, chloroplast, cell wall, vacuole
Group C: diffusion, osmosis, passive transport, active transport, isotonic, hypotonic, hypertonic
Group D: mitosis, interphase, prophase, metaphase, anaphase, telophase, cytokinesis

2. All of the readings should be read with the goal of being able to discuss/explain the information contained in them. The cell unit reading is divided up into two pdf files. You may access them by clicking the buttons to the left.
3.Know all the material covered in class notes.
4. The following labs should be handed in with discussion questions written out and answered in complete sentences. Conclusion, if assigned, should include restatement of purpose, summary of data, data interpretation, and evaluation of hypothesis.

Intro to the Microscope Observing Cells
Diffusion Lab Cell snacking
Mitosis lab Cell size lab?

5.Have the following expectation questions answered in your notebook. Be sure to label the group number with your questions

Group 1 Discovery of Cells
1. Why was the development of microscopes necessary for the study of cells?
2. Compare the way images are formed in light microscopes and electron microscopes.
3. How are prokaryotic cells and eukaryotic cells different?
4. What are the three main ideas of the cell theory?
5. How did the use of stains advance the study of cells?

Group 2 Eukaryotic Cell Structure

  1. What is the advantage of the highly folded membranes in a cell?
  2. Make an organelle study table. Include their location and function.
  3. What organelle would be especially numerous in a cell that produces large amounts of protein products?
  4. What organelle would be especially numerous in a cell that does a great deal of work like a muscle cell?
  5. Why is the structure of the plasma membrane referred to as a bilayer and as a fluid mosaic structure?

Group 3 Moving stuff

  1. Explain how osmosis and diffusion are alike and how they are different.
  2. Compare and contrast active transport and facilitated diffusion.
  3. Cells in the human body constantly use oxygen during metabolism. Blood contains oxygen. Why does oxygen diffuse into the cells from the bloodstream?
  4. In what ways is the size of cells determined by diffusion?

Group 4

  1. Describe the nuclear activities during
    1. Interphase
    2. Prophase
    3. Metaphase
    4. Anaphase
    5. Telophase
  2. What is the role of the spindle fibers in mitosis?
  3. Why is it necessary for a cell’s chromosomes to be distributed to its daughter cells in such a precise manner?
  4. Contrast the differences in plant and animal cytokinesis.
  5. At one time, interphase was referred to as the resting phase of the cell cycle. Why do you think this description is no longer used?

6. Know how to convert from one unit to another in the metric system using factor label method.
7. Organelle Activity
8. Know all organelles, their location in the cell and their function.
9. Be able to recognize the different stages of mitosis in a prepared microscope slide.

Extra Credit: All homework must be turned in on time for this chapter in order to be eligible. Must be turned in before taking the test. (maximum 2 pts on test)

Activity 1: Do the online review test for the first cell test and submit it to me for credit. If you get an 80 or better on the test, you will get 2 points on your first cell test. To access the review test, follow the link below:

After submitting the test, if you will be told your score and the correct answers for the ones you got wrong.

Activity 2: Do the online review test for the second cell test and submit it to me for credit. If you get an 80 or better on the test, you will get 2 points on your second cell test. To access the review test, follow the link below:
