Hypothesis: The larger the cell is‚ the more difficult it will be for the chemicals to reach the centre of the cell‚ and diffuse throughout it. This is because there will be a higher surface-area to volume ratio in the larger cells‚ making the centre of the cells further away from the surface. Therefore‚ when dipped in sodium hydroxide‚ the larger cells will not
