endocytosis
phagocytosis
pinocytosis
exocytosis
12
Passive transport
moves particles from a high to a low concentration.
doesn't require energy.
moves particles against a concentration gradient.
requires energy.
13
Active transport
is usually done by transport proteins in the cell membrane
moves materials against a concentration gradient
all of the answers are correct
requires energy
14
Requires energy; materials enter pockets in cell membrane, then forms vacuole in cytoplasm
endocytosis
pinocytosis
exocytosis
phagocytosis
15

hydroponic
isotonic
hypertonic
hypotonic
17
Equilibrium is reached
at the end of active transport.
when movement of particles stops.
only during passive transport.
when particles are evenly distributed through the space.
18
The
primary
function of the cell membrane is
cell signaling.
to control what moves in and out of the cell.
