Experiment to Investigate Osmosis in Potatoes
The aim of this experiment is to investigate the movement of water in and out of plant cells. The cells chosen for study will be taken from potato tubers. Firstly I will explain what osmosis is. Osmosis is the passage of water from a region of high water concentration through a semi permeable membrane to a region of low water concentration. This definition contains three important statements:
showed first 75 words of 2830 total
showed last 75 words of 2830 total
of concentrations to investigate furthur and increase accuracy. I would also increase the repetitions to 5 per molarity and increase the molarity to try and find the point of plasmolysis. I could also decrease the range between each molarity (every 0.05 for example) to try and find the exact concentration of the potato cells where there is not net gain. This investigation was succesful but could still be made more accurate by some of the above ways.
