osmosis Flashcards
1
Q
define osmosis
A
movement of water from an area of high to low concentration across a semi permeable membrane
2
Q
explain the method of observing the effect of sugar solutions
A
1) cut potato
2) get 2 beakers one with pure water one with concentrated sugar solution
3) measure mass of potato +put into beaker
4) leave for 24 hrs
5) take them out and dry
6) remeasure mass
3
Q
what are the outcomes of the experiment
A
if mass has increased the water has moved into potato cell
if mass has decreased the water has moved out of the potato cell
4
Q
what is the only think you should change in this experiment
A
concentration of sugar solution
