Answers
1
Diffusion of water across a selectively permeable membrane
isotonic
hypertonic
osmosis
hypotonic
2
During diffusion, molecules tend to move in what direction?
direction that doesn't depend on concentration gradient
low to high concentration
molecules never move
high to low concentration
3
What process is being shown the image?
exocytosis
facilitated diffusion
osmosis
cell membrane pump
4
The sodium-potassium pump transports which of the following
Na out of the cell and K into the cell
Na into the cell and K out of the cell
both Na and K out of the cell
Both Na and K into the cell
5
When the relative concentrations on each side of selectively permeable membrane are even
equilibrium
isotonic
hypertonic
water molecules still continue to flow in and out
6
Which process do some animal cells use to engulf, digest, and destroy invading bacteria?
pinocytosis
exocytosis
phagocytosis
all the above
7
Sugar has to enter the cell through
simple diffusion
endocytosis
carrier proteins
facilitated diffusion
8
Which structure allows plants cells to not burst in a hypotonic solution?
vacuoles
cell membrane
cell wall
chloroplasts
9
Single celled aquatic organisms deal with excess or lack of solutes through which organelle?
contractile vacuole
mitochondria
perixosomes
lysosomes
10
Animal cells will burst in hypertonic conditions. This is called
plasmolysis
hemolysis
cytolysis
turgor
11
How do cells get rid of waste?
phagocytosis
endocytosis
pinocytosis
exocytosis
12
Active transport requires
no energy
vitamins
energy
cofactors
13
Ion channels aid the movement of which substances?
molecules up a concentration gradient
water across a cell membrane
carrier proteins within the lipid bilayer
ions across a cell membrane
14
passive transport : osmosis :: active transport : _____________________
endocytosis
diffusion
cytolysis
ion channel
15
Putting sugar in a hot cup coffe will result in
sugar floating to the top
most of sugar sinking to the bottom
sugar forming a clump
sugar spreading out relatively even
16
Pinocytosis is involved in
intake of large particles
passive diffusion
intake of fluids
destruction of bacteria
17
Preferred solution state for plant cells
lysed
hypotonic
hypertonic
isotonic
18
Which description about this experimental setup is correct?
right side contained more solute so water left
right side contained more solute so water entered
Solutes entered the right side
left side contained more water molecules so water stayed
19
A cell contains 25% solute. The solution surrounding it contains 50% solute
the cell is hypotonic
water will leave the cell
water will enter the cell
the cell is hypertonic
20
Carbon dioxide and oxygen
must enter cells through protein channels
can pass through the phospholipids
use active transport
use simple diffusion
