Question

cylinders of potato will be incubated in sucrose solutions of various molarity. what will happen before and after incubation?
a) heating of the potato cylinders
b) observation under the microscope of the potato cylinders
c) staining the potato cylinders with methylene blue
d) weighing of the potato cylinders

Explanation:

To determine the effects of incubation in sucrose solutions of various molarities on potato cylinders, weighing them before and after is a common method to observe water - movement (osmosis). Heating would change the properties of the potato cells and is not a typical pre - or post - incubation step for this experiment. Observation under the microscope and staining are more for examining cellular structures rather than a direct way to assess the overall effect of the sucrose solutions on the potato cylinders in terms of osmosis.

Answer:

d) Weighing of the potato cylinders
