diffusion
facilitated diffusion
7
Which of these is selectively permeable?
a strainer
all of these are selectively permeable

8
What is concentration?
amount of things in a given area
the amount of mass something has
the density of a substance
the weight of a substance
9
Equilibrium is reached
when movement of particles stops.
at the end of active transport.
only during passive transport.
when particles are evenly distributed through the space.
10
Passive transport
moves particles from a high to a low concentration.
requires energy.
doesn't require energy.
moves particles against a concentration gradient.
11

16
Requires energy; vacuole fuses with membrane, contents forced
out of cell
= ?
phagocytosis
exocytosis
endocytosis
pinocytosis
17
A cell is in a ____solution when: size doesn't change; water goes in and out at the same rate
hydroponic
hypotonic
isotonic
hypertonic
18
__________ is the diffusion of water through a semipermeable membrane.

all of the answers are correct
is usually done by transport proteins in the cell membrane
requires energy
moves materials against a concentration gradient
