Chapter 7 BFQ  (scroll down to find other sections)

Chapter 7.1

1. Define a cell. What are the three parts of cell theory? What are the names of the 3 scientists who came up with the 3 parts of cell theory?

2. Draw a Venn diagram comparing prokaryotes (chpt 7), eukaryotes (chpt 7) and viruses (chpt 19.2) make sure you list all the structures and organelles that fit in each category.

Example of a triple Venn diagram

Chapter 7.2

3. List the different types of microscopes, what level of magnification goes with each type of microscope.

4. Create a "Data Table for Cell Organelles" and fill in the information requested (please do this in your journal)

Organelle Name or Structure name

Draw basic shape; label parts in reference to the cell membrane

Give a simple description of makeup (type of biomolecule(s) and which types of cells contain this organelle or structure)

Name function or purpose of organelle or structure

Make an analogy that helps explain the organelle or structure (for example: a cell wall is like a fence around a house, the fence provides some structure and helps keep out some materials... of course now you can't use this example

Chpt 7.3

1.  Why is the cell membrane sometimes called the plasma membrane?

2.  What is the function of the cell membrane?

3. What does the lipid bilayer provide for a cell?

4. Look at Figure 7-12; describe the position of the proteins in relationship to the lipid bilayer.

5. Why is the membrane called a "fluid mosaic model"?

6.  What functions do cell membrane bound proteins have?

7. What is the function of carbohydrates in the cell membrane?

8.  What organisms produce cell walls (in addition to already having a cell membrane)?

9. Is the cell wall impermeable to substances such as water, oxygen and carbon dioxide?

10. What is the function of the cell wall?

11.  What are most cell walls composed of?

12. Read about "Measuring Concentration" on pg. 183; why is the first solution twice as concentrated as the second solution?

13. Why do particles tend to move from an area of higher concentration to lower concentration?

14.  Why doesn't diffusion require cell energy?

15.  Once equilibrium is reached, do the particles of the solution stop moving?

16.  What is the difference between a permeable membrane and an impermeable membrane?

17.  What is a selectively permeable membrane?

18.  What are the two main points of osmosis?

19.  After reading about "How Osmosis Works" and looking at Figure 7-15, explain why the water level in the beaker went up on the left side of the membrane.

20.  Compare diffusion to facilitated diffusion: how are they the same, how are they different?

21. What is active transport?

22. How are small molecules and ions actively transported across a cell membrane?

23.  How are large molecules and clumps of materials actively transported across a cell membrane?

24.  What is the difference between pinocytosis and phagocytosis?

25.  What is the difference between endocytosis and exocytosis?

Chpt 7.4 includes 18-1, 18-3, 471-472 (part of  19-1) and 478-479 (part of 19-2).

1. If all living things are composed of cells and have the same basic chemistry and genetic material, why is there such a great diversity of living organisms on the earth?

2.  How is a unicellular organism just like you?

3.  What do all multicelluar organisms depend upon?

4.  What is cell specialization?

5. Read about "specialized animal cells" and explain one of the examples (either pancreatic cells or muscle cells).

6. What is the level of organization in multicelluar organisms?

7.  Explain what a tissue is.

8.  Explain what an organ is.

9.  Explain what an organ system is.

10.  What is the advantage of having this hierarchy of organization? 

18-1, 18-3, 

1. What is taxonomy?

2. What is binomial nomenclature?

3. Translate: DKPCOFGS which taxon is new?

4. What are the 5 kingdoms?  Which kingdom is now divided into 2 domains?

5. Copy Figure 18-12. Define unicellular, multicellular, autotroph, and heterotroph.

6. Which domain contains the most kingdoms. Name those kingdoms.

Pages 471-472 (part of  19-1)

7. List the major differences between Kingdom Eubacteria and Kingdom Archaebacteria.

Pages 478-479 (part of 19-2).

8. What are the major structures of a virus, provide a labeled diagram.
