Question 14

A student places a swede strip in a concentrated sucrose solution. The strip loses mass.

The student removes the strip and weighs it without blotting its surface dry. The measured decrease in mass is smaller than the actual decrease in the mass of the tissue.

Why is the measured decrease smaller?

[1]
A

Sucrose solution left on the surface increases the measured final mass

B

Sucrose enters the strip by osmosis and replaces the water that was lost

C

The strip reaches the same water potential as pure water when it is removed

D

Water inside the strip evaporates and increases the measured final mass
