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