Question 8

A student was investigating osmosis in sweet potato cylinders.

They used the following method:

  • Use a cork borer to cut sweet potato into cylinders of equal length and diameter.
  • Record the initial mass of each cylinder.
  • Place each cylinder into a boiling tube containing a different concentration of sucrose solution.
  • Leave the cylinders in the solution for 45 minutes.
  • Remove the cylinders, gently pat them dry with a paper towel, and record the final mass of each cylinder.

Name one variable, other than the dimensions of the cylinders or the immersion time, that needs to be controlled during this investigation.
