Report Membrane Transport Paper The glass slide is slowly lowered down on the epidermal layer using the needle; . The onion cells are examined through the microscope; 4. The structure of the onion cells is drawn as observed under the microscope. Results Observations: In the hypotonic solution the water will move from the solution to the onion cells which will become bigger. PART 2 1. The distilled water is removed using the filter paper; 2. A drop of 5% of sucrose solution is placed at a side of the cover slip and the solution across the epidermal layer is drawn by placing filter paper on the other side of the cover slip; 3. The onion cells are examined once again through microscope. The structure of the onion cells is drawn as observed under the microscope. In the isotonic solution, there is no difference in the similarity, no change in the cells sizes. PART 3 1. Repeat step (1 -3 of PART 2) using 30% of sucrose solution.
