This was an experiment designed to demonstrate the effects of osmosis on a cell, in this case an onion cell. Method:
The onion cells soaked in water The onion cells soaked in sucrose We also used this experiment as an opportunity to practising our microscopy work by measuring the cells using a graticule and a rulered eye piece. We can use this equation to work out the actual size of our cell. We can calculate the image size from the graticule in the lens. and then once we know this we can measure the cell using the ruler on the eyepiece and use the equation to work out the actual size of the cell.
