DIFFUSION

IS THE RANDOM MOVEMENT OF MOLECULES

THERE IS A NET MOVEMENT OF MOLECULES FROM AREAS OF HIGH CONCENTRATION TO AREAS OF LOW CONCENTRATION

OSMOSIS

IS THE DIFFUSION OF WATER MOLECULES

FROM AREAS OF HIGH WATER CONCENTRATION TO AREAS OF LOW WATER CONCENTRATION

0.2% SALT SOLUTION (So 99.8% water) 7 % SALT WATER SOLUTION ( so 93% water) WHICH WAY WILL WATER MOVE??

0.2% SALT SOLUTION 7 % SALT SOLUTION WATER WILL MOVE OUT OF THE FISH H20

THIS RESULTS IN PLASMOLYSIS THE LOSS OF FLUID FROM CELLS. THIS IS WHY YOU DO NOT PUT FRESH WATER FISH IN A SALT WATER TANK

4% SALT SOLUTION IN FISH (96% water) 0.1 % SALT WATER SOLUTION (99.9% water )

4% SALT SOLUTION IN FISH 0.1 % SALT WATER SOLUTION WHICH WAY WILL WATER MOVE?

4% SALT SOLUTION IN FISH 0.1 % SALT WATER SOLUTION WATER WILL MOVE INTO THE FISH H20

THIS RESULTS IN CYTOLYSIS CELLS BURSTING FROM TAKING IN TOO MUCH WATER

Hypertonic Hypotonic Isotonic

Hyper – too much hyperactive hyperthermia hyperglycemia

Hypertonic – describes A solution with more Solute than another solution

Hypo – too little hypoactive hypothermia hypoglycemia

Hypotonic – describes A solution with less Solute than another solution

Distilled water Salt water Which is hypertonic? Which is hypotonic?

Saltwater Tapwater Which is hypertonic? Which is hypotonic?
