okay, so i conducted this experiment at school.
There were 6 beakers. each had a sucrose solution: 0.2M, 0.3M, 0.4M, 0.5M, 0.6M and 0.7M respectively.
In each beaker of sucrose solution there were some pieces of red onion.
We had to get one piece of onion from each beaker and peel off the epidermis. We then had to examine the epidermis from each onion under a microscope and count how many cells had plasmolysed in each of them.
It was found that the onions that were soaked in 0.2M, 0.3M and 0.4M sucrose solution had a low amount of plasmolysed cells, about 0% to 16%.
However, onions that were soaked in the 0.5M, 0.6M and 0.7M sucrose solution had a high amount of plasmolysed cells, about 50% to 100%.
