Question

question 1. if starch (solute) cannot move through a membrane, which observation would most likely be made 24 hours later? a. the mass of the “model cell” has increased b. the amount of distilled water in the beaker has increased c. the “model cell” has become smaller d. the contents of the “model cell” have changed color

Explanation:

Osmosis occurs when water moves from an area of lower solute concentration (distilled water) to an area of higher solute concentration (starch - filled model cell). Since starch cannot pass through the membrane, water will enter the model cell, increasing its mass.

Answer:

A. The mass of the "model cell" has increased
