Aim: to investigate the effect of concentration of a sugar solution on the rate of osmosis in a potato and the effect on mass and length OSMOSIS IS THE PROCESS BY WHICH CELLS EXCHANGE WATER WITH THEIR ENVIRONMENT. IT IS A PASSIVE PROCESS. DEFINITION: the net movement of freely moving water molecules from a region of high concentration to a region of lower concentration through a semi permeable membrane. Solute molecule Hypo hyper Molecular view of osmosis Membrane Water moves to equalise solute concentration RESULTS Test One Mass Of Potato At Start (g) Length Of Potato at Start (cm) Concentration Of Sucrose (M) Time (Minutes) Mass Of Potato At End (g) 7.038 5 0.0 30 7.924 7.880 5 0.1 30 7.989 7.984 5 0.2 30 7.986 7.735 5 0.3 30 7.872 7.756 5 0.4 30 7.695 7,735 5 0.5 30 7.650 7.722 5 0.6 30 7.715 7.665 5 0.7 30 7.807 7.736 5 0.8 30 7.753 7.789 5 0.9 30 7.682 7.849 5 1.0 30 7.736 Test Two Mass Of Potato At Start (g) Length Of Potato (Cm) Concentration Of Sucrose (M) Time (Minutes) Mass Of Potato At End (g) 8.077 5 0.0 30 8.114 7.807 5 0.1 30 7.752 7.910 5 0.2 30 7.889 8.017 5 0.3 30 7.882 7.776 5 0.4 30 7.883 7.818 5 0.5 30 7.713 7.819 5 0.6 30 7.751 7.781 5 0.7 30 7.724 7.707 5 0.8 30 7.727 7.839 5 0.9 30 7.634 7.531 5 1.0 30 7.695 Test Three Mass Of Potato At Start (g) Length Of Potato At Start (cm) Concentration Of Sucrose (M) Time (Minutes) Mass Of Potato At End (g) 7.994 5 0.0 30 7.859 7.897 5 0.1 30 7.862 7.774 5 0.2 30 7.857 7.861 5 0.3 30 7.687 7.753 5 0.4 30 7.937 7.934 5 0.5 30 7.751 7.803 5 0.6 30 7.798 7.800 5 0.7 30 7.856 7.792 5 0.8 30 7.760 7.813 5 0.9 30 7.716 7.820 5 1.0 30 7.914 Difference Concentration...
