Osmosis in potato cylinders coursework

Set up a series of boiling tubes with each of these solutions. Make sure each tube is labelled with the concentration.

Prepare a blank results table before you begin. Make sure when weighing the potato cylinders, that their masses are not mixed up when recording them.

Each cylinder will have a different mass before and after the investigation.

Osmosis in potato cylinders coursework

Dry a potato strip using a paper towel. Measure the mass of the potato cylinder. Remove the potato strip, dry it carefully using paper towel.

Measure and record the mass of the potato strip. Repeat for each sucrose concentration.

Potato Osmosis by Darrien Saveski on Prezi

For each sucrose concentration, repeat the investigation for several potato cylinders. This allows you to check the precision of your results results that are close together for the same concentration suggest that the results are precise.

The potato cylinders might not all behave in the same way. Making a series of repeat experiments means that any anomalous results can be identified and ignored when a mean is calculated.

Risks Make sure that the potato is placed on a ceramic tile when using the cork borer — do not cut the potato cylinders. Care must be taken when using the scalpel. Wear eye protection when using chemical solutions. Results This experiment shows the effect of osmosis on plant tissue.

The cylinders will decrease or increase in mass if they lose or gain water by osmosis.In this coursework experiment I plan to find the rate of osmosis in different vegetables (Carrot, Potato, Swede, Parsnip and Sweet Potato). I will measure the mass before and after the experiment to use the results to calculate the rate of osmosis, and to find trends in the vegetables.
