RP-effect of osmosis on plant tissue

• what is the method?

  1. Prepare a range of sucrose (sugar) solutions.
  2. Set up a series of boiling tubes with each of these solutions. Also, set up one containing distilled water. This will have a concentration of sucrose of 0 and will act as the control in the experiment.
  3. Carry out the investigation weigh the potato cylinders. Each cylinder will have a different mass before and after
  4. repeat the investigation for several potato cylinders. Making a series of repeats means that any anomalous results can be identified and ignored when a mean is calculated.
• what are the risks?

  • Make sure that the potato is placed on a ceramic tile when using the cork borer – do not cut the potato cylinders towards your hand.
  • Care must be taken when using the scalpel.
  • Wear eye protection when using chemical solutions.
• what does this experiment show?

  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.
