Chapter 7 & 8 Test Hints
Remember to bring a four function calculator to the test. You will be expected to do calculations.
Know all the parts of the eukaryotic animal cell that I expect you to know (see website).
Know the main differences between prokaryotic and eukaryotic cells.
Know the main differences between an animal cell and plant cell. Study the illustrations of the animal and plant cell in the book (page 108 and 109) and be able to label these illustrations if asked.
One of the ways we know about the parts of the cell is because of cell fractionation. Read about it and understand it (figure 7.3 is a great summary of how it works. The caption and illustration is as much detail as you need to know).
Know my chapter 8 PowerPoint Lecture very, very well.
I strongly recommend you study the figures in the book that I refer to below, they will really help you understand the processes. Going onto the internet and looking at the animations from the CDROM or other websites would be very helpful. If a picture is worth a thousand words, an animation is worth 10,000!
Know what diffusion is. Know figure 8.9 really well.
Know what facilitated diffusion is. Know figure 8.13 really well.
Know what osmosis is. Know figure 8.10 really well.
Know what active and passive transport are. Study figure 8. 15 really well.
Know the difference between exocytosis, phagocytosis, pinocytosis, and receptor mediated endocytosis. Study figure 8.18 really well.
Know the difference between isotonic, hypertonic, hypotonic. Know what happens when you add different kinds of cells into different kinds of solutions. Study figure 8.11 really well. Know why things happen as they do. Know what plasmolysis is.
To test your knowledge of the material I strongly suggest you review take the multiple-choice exam in the Cliffs Note Book on the cell.
The free response question will be #3, the current model of the cell membrane. You will be expected to draw and label a 2-dimensional illustration of the cell membrane. I expect it to include all the items labeled in figure 8.5 and figure 8.2 but it only needs to be a 2-D drawing.
There will be a separate part of the test where I ask you to work out two water potential problems. They will be similar to the ones you did for HW. I will give you the equations.
Re-read "A Short History of Nearly Everything"
Chapter 18: The Bounding Main- read from beginning of the chapter until the end of the paragraph ending "That is why we don't drink seawater." (about 2.5 pages).
Chapter 24: Cells- read the whole chapter (it is pretty darn short and a good summary of the basics).
Use intelligent study techniques (refer to the Ten Good Rules of Studying).
The test is fair but challenging. You really have to know the material to do well- superficial memorization wont work since you need to understand all the different processes. Good luck!
