Investigating Osmosis with Onion Cells October 4, 2019 In class this week Y10 pupils were investigating the effect of osmosis on red onion cells under the microscope. Pupils added either a drop of distilled water or a drop of sodium chloride solution to onion cells and observed the cells under the microscope.

This is shown by the purple colour in each cell being only in the middle of the ce Krishna (10ER) took this picture of her turgid onion cells. Water has moved into the cells by osmosis and so the cytoplasm is full. This is shown by the purple colour filling each cell.
