K.C.S.E Biology Q & A - MODEL 2006PP1QN12
An experiment was set up in the experiment as show below.
The set up was left for 30 minutes.
a) State the expected results.
b) Explain your answer in (a) above
(a) Visking tubing will become turgid; accept will increase in volume / bulges/ swells/ becomes bigger/ expands.
(b) Sucrose solution is hypertonic/ water is hypotonic; water moves from beaker into visking tube by osmosis though semi permeable visking tubing, making visking tubing turgid.
Or water moves from beaker into visking tubing by osmosis, through semi permeable visking tubing; with hypertonic solution.
