Answers
1
Requires energy; materials enter pockets in cell membrane, then forms vacuole in cytoplasm = ?
osmosis
diffusion
endocytosis
exocytosis
2
Equilibrium is reached
when particles are evenly distributed through the space.
when movement of particles stops.
at the end of active transport.
only during passive transport.
3
Requires energy; vacuole fuses with membrane, contents forced out of cell = ?
exocytosis
phagocytosis
pinocytosis
endocytosis
4
A cell is in a ____solution when: size doesn't change; water goes in and out at the same rate
hydroponic
hypotonic
isotonic
hypertonic
5
Which of these is selectively permeable?
a cell membrane
a window screen
a strainer
all of these are selectively permeable
6
Another name for the cell membrane is
the nuclear membrane
the cell wall
the plasma membrane
the endocytic barrier
7
Water enters, cell swells; lower solute concentration outside the cell than inside = __solution
hypotonic
isotonic
hypertonic
hydroponic
8
What kind of solution is the red blood cell on the right in?
isotonic
hypotonic
hypertonic
hydroponic
9
What is structure "D"?
a glucose molecule
cholesterol
a protein
a phospholipid
10
The stuff that is dissolved is the _________.
solution
solute
solvent
suspension
11
__________ is the diffusion of water through a semipermeable membrane.
active transport
osmosis
exocytosis
facilitated diffusion
12
What kind of transport doesn't require the use of energy to move materials across the membrane?
facilitated diffusion
diffusion
all of these don't require the cell to use energy
osmosis
13
The primary function of the cell membrane is
cell signaling.
to control what moves in and out of the cell.
to protect the cell
to provide support for the cell.
14
"A" is
a protein
a polar phosphate
cholesterol
a nonpolar fatty acid
15
Movement of particles from an area of high concentration to an area of lower concentration is:
osmosis
endocytosis
diffusion
equilibrium
16
What kind of solution is the red blood cell on the left in?
hypotonic
hypertonic
isotonic
hydroponic
17
The stuff that does the dissolving is the __________.
suspension
solvent
solution
solute
18
Passive transport
requires energy.
doesn't require energy.
moves particles from a high to a low concentration.
moves particles against a concentration gradient.
19
What kind of solution is the red blood cell in the middle in?
hydroponic
hypertonic
hypotonic
isotonic
20
The basic structure of the cell membrane is
made of proteins.
a phospholipid bilayer.
a liquid bilayer.
impermeable.
21
What molecules are imbedded in the bilayer?
proteins
ribosomes
glucose
nucleic acids
22
Water leaves, cell shrinks; higher solute concentration outside cell than inside = ? solution
hypotonic
hypertonic
hydroponic
isotonic
23
Active transport
moves materials against a concentration gradient
requires energy
is usually done by transport proteins in the cell membrane
all of the answers are correct
