INVESTIGATING THE FACTORS AFFECTING THE WATER RELATIONS OF PLANT CELLS By Emily Akena INVESTIGATING THE FACTORS AFFECTING THE WATER RELATIONS OF PLANT CELLS Introduction This investigation studies the affect of different variables on the rate of osmosis in plant cells. The variables that would affect this investigation are: * Surface Area * Temperature * Concentration of surrounding solution * Concentration of solutes inside plant * Plant tissue - age, species, time of year The plant tissue to be used in this investigation is potato tuber tissue, because handling it is simple. The variable that will be investigated is the effect of concentration on the water relations of the potato cells as the concentration can be varied and measured accurately. Visual results can also be obtained. Temperature will not be varied, as it is hard to control and would therefore lead to inaccurate results. Temperatures that are too high will cause the proteins in the cell walls to be denatured and the plant to...
