The biology essay topics help us to understand ecology, diseases, genetic procedures but also other interesting topics that enable us to comprehend. EXERCISE 2 - Determining the Water Potential of Potato Cells. In animal cells, the movement of water into and out of the cell is influenced by the relative concentration of solute on either side of the cell membrane. If water moves out of the cell, the cell will shrink. If water moves into the cell, the cell may swell or even burst. Investigating osmosis - coursework for biology includes prediction evaluation and results solution. So when a cell is placed in distilled water (high water concentration) water will move across the semi-permeable membrane into the cell (lower water concentration) by osmosis, making the cell swell.
