Instructions: Answer all questions to get your test result.
1) What is endocytosis?
A
When a cell gets rid of particles of waste.
B
When a cell expands.
C
When a cell takes in particles.
D
When a particle expands in the cell.
2) Osmosis
A
is the movement of water across a membrane
B
all the answers are correct
C
is like diffusion
D
is an example of passive transport
3) Which of the following is an example of phagocytosis?
A
nerve cells taking in small dissolved neurotransmitters
B
white blood cells engulfing bacteria
C
hormones leaving pitutitary cells via vesicles
D
water leaving the cell via carrier proteins
4) What is equilibrium?
A
Moving from a higher concentration to a lower concentration
B
Moving from a lower concentration to a higher concentration
C
When there is different concentration on both sides
D
When the concentration of substances are the same on both sides
5) What is diffusion?
A
Movement of water molecules
B
keeping internal conditions stable or balanced
C
Movement of molecules across the cell membrane from low concentration to high concentration
D
Movement of molecules across the cell membrane from high concentration to low concentration
6) Filtration
A
used to allow a liquid to seep through a substance that traps larger particles....a passive transport process
B
won't dissolve in water at all...an active transport process
C
molecules that have been dissolved into other molecules to form a solution...a passive transport process
D
has a large amount of solute in the solvent...an active transport process
7) Selectively permeable membrane
A
movement of molecules across a membrane and this movement requires energy
B
A substance that changes color in the presence of a particular compound
C
How the nucleolus chooses what may enter or exit the cell
D
allows certain molecules to pass through but not others
8) . Which of the following occurs in pinocytosis?
A
large molecules move into the cell only
B
solutes or fluids move into/out of the cell
C
large molecules move out of the cell
D
solutes or fluids move out of the cell
9) What similarity do phagocytosis and pinocytosis share?
A
Both processes move molecules out of cells by using energy.
B
Both processes move molecules out of cells without using energy.
C
Both processes use energy (ATP).
D
Both processes move molecules into cells without using energy.
10) This type of passive transport, pushes nutrient molecules down' a concentration gradient
A
pinocytosis
B
diffusion
