The Cell-A Tour of the Cell (6), Membrane Structure and Function (7)
1. Compare and contrast prokaryotic and eukaryotic cells.
2. Explain the significance of organelles. What are the costs and benefits of having large compartmentalized cells?
3. What is the primary function of a cell membrane? What characteristics of membranes allow them to contribute
to metabolic activity?
4.
The organelles that contain their own DNA are all enclosed in double membranes. Relate this observation to the
endosymbiotic theory.
5. Explain the fluid mosaic model.
6. The cell membrane is selectively permeable. Explain what that means. Which molecules easily cross the
membrane? How are molecules transported that do not easily cross the membrane?
7.

Isotonic
8. What is happening in the diagram below? Explain.
9.
What do animal & plant cells do when placed in solutions that are: (draw diagrams for each showing movement
of molecules)
a. Hypotonic
b. Hypertonic
c. Isotonic
11. Explain the graph as it relates to the lab we did using potatoes placed in varying solutions of sucrose. What were we
able to determine?
12. Trace the path of production of a protein-based secretion from a secretory cell. (Label the structures involved)
