What To Know
1. Structure of the Cell Membrane, Cell Wall and Cytoskeleton
a. Phospholipids (how they are hydrophilic/phobic and polar/non-polar)
b. Proteins (three types…)
c. Cholesterol (what does it do?)
2. Types of Transport
a. Brownian Motion and Equilibrium
b. Active vs. Passive transport:
i. Diffusion/Facilitated Diffusion/Osmosis (PASSIVE)
ii. Protein Pumps/Endocytosis/Exocytosis (ACTIVE)
3. Cellular Environments (how are cells going to be impacted?)
a. Solute concentrations:
i. Hypertonic/Hypotonic/Isotonic
b. Turgor Pressure and plasmolysis in plant cells

Questions and Content for Review:
1.
The size and characteristics of solutes/molecules determine whether or not materials are able to
pass into or out of a cell by passive transport.
Review Question: What types of molecules can easily pass through the cell membrane through passive transports?
Review Question: What types of molecules cannot easily pass through, and must use active transport, or not pass
through at all?
2.
Materials move within cells or solutions until dynamic equilibrium is reached. Sometimes a cell
does not have equilibrium, and there is a concentration gradient.
Review Question: How does osmosis or diffusion allow a cell to establish equilibrium with its environment?
3.
Isotonic, hypertonic, and hypotonic solutions all describe the concentration of solutes in the
solution outside the cell.
4.
Be able to determine which way water will diffuse (into or out of a cell) depending on the type of
solution it is in. The SOLUTE DOES NOT MOVE. Rather, the water will move into/out of a
cell to balance the concentration gradient. Result: Equilibrium!
-Osmotic Pressure, describe below:
-Turgor Pressure, describe below:
-Plasmolysis in Plant cells
Describe them here:
vs. Lysis in Animal cells
Passive transport relies mostly on Brownian motion and natural concentrations gradients that exist
in nature.
Define each:
Diffusion
Facilitated Diffusion
Osmosis

In contrast to passive, ACTIVE TRANSPORT, must rely on the usage of energy for the transport
of certain materials against a concentration gradient, or because they are too large.
Define Each:
Protein Pumps
Exocytosis/Endocytosis
Phagocytosis/Pinocytosis
Cell Transport Practice Problems: The following are practice problems that ask you to figure out
what impact each situation will have on cells:
In questions 1 and 2, there is a semipermeable membrane separating each solution.
1. Which salt solution is more concentrated? Solution A has 18grams of salt in 6Liters of water.
Solution B has 24g of salt in 12L of water. Show your work.
Which direction would water move and why?
2. Which sucrose solution is more concentrated? Solution A has 7g of sucrose in 2L of water.
Solution B has 49g of sucrose in 14L of water. Show your work.
Which direction will water move, and why?
3. Human blood cells have a concentration of approximately 0.7% NaCl. What would happen to
human blood cells if they were placed in a solution with a concentration of 2.9% NaCl? Explain
WHY.
4. What would happen to human blood cells if they were placed in a solution with a concentration
of 0.7% NaCl? Explain. Which direction would water move? Explain.
5. What would happen to human blood cells if they were placed in a hypotonic solution of NaCl?
Explain. Which direction would water move? Explain.
