6.4 Specialized Cells Flashcards
1
Q
osmosis
A
the diffusion of water across a semi-permeable membrane
2
Q
water diffuses from higher to
A
lower concentration
3
Q
Water follows
A
Solute
4
Q
when the solute dissolves in the
A
solvent, it makes a solution
5
Q
hypertonic
A
higher in solute
6
Q
when a cell is in a hypertonic solution
A
it will shrink
7
Q
when a cell is in a hypotonic solution,
A
it will swell
8
Q
hypotonic
A
lower in solute
9
Q
isotonic
A
same solute concentration
no change in water
10
Q
simple diffusion
A
particles move directly across the membrane
11
Q
simple diffusion moves
A
small nonpolar molecules
12
Q
facilitated diffusion
A
involves a carrier protein
13
Q
facilitated diffusion moves
A
polar molecules
14
Q
in diffusion, molecules move from
A
high to low concentration
15
Q
active transport
A
cells move molecules against concentration gradient
