Investigating the relationship between diffusion and Size of the Cell
Investigating the relationship between diffusion and Size of the Cell
Aim: To confirm the relationship that diffusion of chemicals depends on the ratio of surface area: volume.
Hypothesis: I believe that the rate of diffusion will decrease with the increase in the volume of the cell.
Fair Test:
- Two agar cubes were used for each of the two volumes so that more accurate results could have been obtained.
- All agar cubes were of the same size, this was done by using a ruler when cutting the agar.
- All jelly samples were taken from one whole jelly container so the cells will be similar and the depth would remain the same.
- The temperature will remain the same for all beakers.
Safe Test:
- We will be using scalpel to cut the jelly therefore we made sure we handled them with care
- We made sure we used the beakers appropriately, so that they did not brake and cause any damage.
