Question

how long do the potato cylinders need to incubate in the various solutions of sucrose?
a) 1 minute
b) 10 minutes
c) 30 minutes
d) 1.5 to 2 hours

Explanation:

In typical osmosis - related experiments with potato cylinders in sucrose solutions, sufficient time is needed for osmosis to occur. 1 minute and 10 minutes are too short for significant osmotic changes. 30 minutes may also not be enough for a full - scale osmotic equilibrium in many cases. Usually, 1.5 to 2 hours allows for proper water movement across the potato cell membranes in different sucrose concentrations.

Answer:

d) 1.5 to 2 hours
