Unit 2: Cells- osmosis Flashcards
(8 cards)
1
Q
osmosis
A
diffusion of water
2
Q
hypertonic solution
A
more solute, less water
3
Q
hypotonic solution
A
less solute, more water
4
Q
isotonic solution
A
solute = water
5
Q
animal cell reaction to different tonicities
A
hypertonic- shrivel (lose h2o)
isotonic- normal (lose+gain h2o =ly)
hypotonic- lyse/explode (gain h2o)
6
Q
tonicity
A
ability of a solution to cause cell to lose/gain water
7
Q
plant cell reaction to different tonicities
A
hypertonic- shrivel (lose h2o)
isotonic- flaccid (lose + gain h2o =ly, not enough pressure on cell wall)
hypotonic- normal (gain h2o but cell wall stabilizes pressure)
8
Q
in osmosis water moves from ________ concentration of water to ________ concentration of water
A
high to low
