small nonpolar molecules
small polar molecules
2
Which of the following is an example of passive transport?
facilitated diffusion
sodium/potassium pump
exocytosis
endocytosis
3
Which term describes the relatively constant internal physical condition of an organism?
organ system
unicellularity
homeostasis
cell specialization
4
Which movement of substances through a cell membrane requires energy?
osmosis
active transport
facilitated diffusion
diffusion
5
When is dynamic equilibrium reached?
when the rate of change in the solution slows by one half
when the molecules are mixed and stop moving
when the movement of molecules stops being random
when the concentration is the same on both sides of the membrane
6
What is the main component of the cell membrane?
proteins
lipids
nucleic acids
carbohydrates
7
A cell that is placed in a hypotonic solution will:
gain water
stay the same
lose water
8
Which of the following types of cell transport requires energy?
osmosis
facilitated diffusion
diffusion
sodium potassium pump
9
What is osmosis?
diffusion of glucose across the cell membrane
sleeping on a textbook and acquiring knowledge
there is no such thing as osmosis
diffusion of water across the cell membrane
10
Which type of cell transport requires energy?
active transport
passive transport
11
An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes
solutes to move out of the cell
water to move out of the cell
water to move into the cell
solutes to move into the cell
12
During diffusion, when the concentration of molecules on both sides of the membrane are the same
they will move out of the cell
they will stop moving
they will move into the cell
they will continue to move in both directions
13
Which part of the cell membrane facilitates the transport of polar or charged substances?
nucleic acids
lipids
carbohydrates
proteins
14
Which means of particle transport is shown in the figure?
exocytosis
protein pump
facilitated diffusion
endocytosis
15
Which type of cell transport moves substances from high to low concentration?
passive transport
active transport
16
Which of the following is a function of the plasma membrane?
break down lipids, carbs, and proteins
keep the cell wall in place
regulate the movement of material in & out of cell
store water, salt, proteins, and carbs
17
The diffusion of water across a selectively permeable membrane is called
osmotic pressure
osmosis
pinocytosis
active transport
18
Which cell membrane structure helps identify the cell?
cholesterol
transmembrane protein
carbohydrate chain
peripheral protein
19
What types of materials are exported from cells during exocytosis?
water and glycerol
small molecules such as carbon dioxide
large molecules like enzymes
charged ions like sodium

channel protein
mitochondria
chloroplast
plasma membrane
21
How do oxygen and carbon dioxide cross the cell membrane?
endocytosis
active transport
facilitated diffusion
simple diffusion
22
Which type of cell transport moves substances from low to high concentration?
passive transport
active transport
