Answers
1
Equilibrium is reached
when movement of particles stops.
only during passive transport.
at the end of active transport.
when particles are evenly distributed through the space.
2
The stuff that is dissolved is the _________.
solution
solute
suspension
solvent
3
Active transport
all of the answers are correct
is usually done by transport proteins in the cell membrane
requires energy
moves materials against a concentration gradient
4
The basic structure of the cell membrane is
impermeable.
a phospholipid bilayer.
a liquid bilayer.
made of proteins.
5
What is concentration?
the weight of a substance
the amount of mass something has
amount of things in a given area
the density of a substance
6
The primary function of the cell membrane is
to protect the cell
cell signaling.
to control what moves in and out of the cell.
to provide support for the cell.
7
Which of these is selectively permeable?
all of these are selectively permeable
a cell membrane
a window screen
a strainer
8
A cell is in a ____solution when: size doesn't change; water goes in and out at the same rate
isotonic
hypotonic
hypertonic
hydroponic
9
Passive transport
requires energy.
moves particles against a concentration gradient.
moves particles from a high to a low concentration.
doesn't require energy.
10
__________ is the diffusion of water through a semipermeable membrane.
active transport
osmosis
exocytosis
facilitated diffusion
11
Another name for the cell membrane is
the cell wall
the plasma membrane
the endocytic barrier
the nuclear membrane
12
Which phrase best describes passive transport?
requires no energy from the cell
requires transport protein pumps
Requires ATP
requires endocytosis or exocytosis
13
What kind of solution is the red blood cell on the right in?
hydroponic
hypertonic
hypotonic
isotonic
14
What molecules are imbedded in the bilayer?
ribosomes
proteins
glucose
nucleic acids
15
Requires energy; vacuole fuses with membrane, contents forced out of cell = ?
exocytosis
phagocytosis
pinocytosis
endocytosis
16
What kind of solution is the red blood cell in the middle in?
isotonic
hydroponic
hypertonic
hypotonic
17
What kind of solution is the red blood cell on the left in?
hydroponic
hypertonic
isotonic
hypotonic
18
What kind of transport doesn't require the use of energy to move materials across the membrane?
diffusion
osmosis
facilitated diffusion
all of these don't require the cell to use energy
19

hydroponic
hypotonic
hypertonic
isotonic
20
Requires energy; materials enter pockets in cell membrane, then forms vacuole in cytoplasm = ?
pinocytosis
exocytosis
endocytosis
phagocytosis
21
Movement of particles from an area of high concentration to an area of lower concentration is:
endocytosis
equilibrium
osmosis
diffusion
22
What is structure "D"?
cholesterol
a protein
a glucose molecule
a phospholipid
23
"A" is
a nonpolar fatty acid
a protein
a polar phosphate
cholesterol
24

suspension
solute
solvent
solution
25

hydroponic
hypotonic
hypertonic
isotonic
