An experiment to determine the osmotic values of Chinese radish and Potato cores. Osmosis is the movement of water from an area of high water potential (?) to an area of low water potential through a selectively permeable membrane. The diagrams above shows that only the water molecules can move quickly through the pores in the selectively permeable membrane. The sugar molecules (glucose arde too big to move through the gaps withease. Since there is a higher water potential on the left-hand side more water molecules will move from right to left, than from left to right. What happens if a cell is placed in pure Water H20: If a plant cell is placed in pure water, water outside the cell will flow into the cell by osmosis as the interior of the cell has a lower water potential than the pure water. The reason why the interior has a lower water potential...
