Cells and Membranes Study Guide (Chapter 4 and 5)
Name:
When studying for your test, review the following questions and review your notes, vocabulary worksheets, egg osmosis lab,
chapter 4 cell quiz, crossword puzzle, cell analogy, etc. The following are only examples of what you might see on your test.
Make sure you spend some time studying!
1. Discuss the similarities and differences between diffusion and osmosis.
2. Water generally travels from (hypertonic to hypotonic /
hypotonic to hypertonic) environments.
3. What would happen to a cell if placed in the following solutions?
a. Isotonic solution:
b. Hypotonic solution:
c. Hypertonic solution:
4. Intravenous solutions (IV Fluids) must be prepared so that they are isotonic to red blood cells. A 0.9 %
salt solution is isotonic to red blood cells.
a. Explain what will happen to a red blood cell placed in a solution of 99.3% water and 0.7% salt.
b. Explain what would happen to a red blood cell placed in a solution of 90% water and 10% salt.
c. What would happen to a red blood cell placed in a hypotonic solution?
5. Describe a plant cell in a hypotonic solution. Why does it respond differently than an animal cell?
6. Draw and describe a plant cell experiencing plasmolysis. What type of a solution (hypo, hyper, iso)
would cause plasmolysis?
7. What are some ways animals have adapted to different osmotic conditions in their cells? (HINT: look in
your notes).
8. Explain what happens to a slug when salt is poured on it.
9. Use the following terms to create a concept map or outline showing how cells maintain homeostasis.
Use the following words: active transport, cell membrane transport, concentration gradient, diffusion,
endocytosis, exocytosis, facilitated diffusion, homeostasis, osmosis, passive transport, and sodiumpotassium pump, exocytosis, endocytosis, phagocytosis, pinocytosis
10. Describe how a cell transports items out of the cell. Use words like active transport, vesicle, cell
membrane, exocytosis, etc.
11. How does the sodium-potassium pump work? The sodium potassium pump pumps ______(#) potassium
ions (into / out of) the cell while it pumps _____(#) sodium ions (into / out of) the cell.
12. Pumps are used by a cell to pump materials (up / down) their concentration gradient.
13. Describe what happened to the shell-less eggs in hypotonic and hypertonic solutions AND eggs placed
in a (hypertonic / hypotonic) solution were likely to gain mass because water traveled (into / out of)
the egg.
14. When American pioneers moved west in the 19th century, they often preserved food, especially meat, by
burying it in casks of salt. Bacteria would land on the salt and would quickly die because water would
move out of them by osmosis. Dried, salted jerky is still very popular. How does the salt keep it
preserved?
15. Know the parts and functions of the above cells AND words associated with cells including:
prokaryote, eukaryote, centriole, vacuole, ribosomes, rough ER, smooth ER, nucleus, nucleolus,
Golgi Complex, cytosol, cell wall, plasma membrane, capsule, fimbriae, flagella, plasmodesma,
chloroplast, central vacuole, lysosomes, peroxisomes, microtubules, microfilaments, vesicle,
cytoskeleton, nucleoid (bacteria), Cell Theory, etc.

16. Try playing some of the review games found at these links:
a. Flash cards (uncheck the box that says both sides and really quiz yourself!)
1. http://quizlet.com/5535796/holt-biology-chapter-3-cell-structure-flash-cards/
2. http://quizlet.com/1230402/passive-transport-flash-cards/
3. http://www.flashcardexchange.com/cards/pre-ap-biology-cell-parts-512482
*I completed this: (YES / NO)
b. You can also try out quiz games like the following:
1. http://www.quia.com/cb/25474.html
2. http://www.sciencegeek.net/Biology/review/U1Membranes.htm
*I completed this: (YES / NO)
17. You can also go to my website (near this week's lesson plans link) and open up the link that says “cell
parts memory game.” You can print out these cards, cut them out, and then test yourself matching them
over and over again. When you print them, functions will be correctly matched with the cell part!
*I completed this: (YES / NO)
18. Most importantly, refer to your cell quiz and your animal cell coloring. Make sure you understand each
of the cell parts and their function. Use your notes to help you, but please also refer to your text to see
additional pictures/descriptions.
