Below are sample questions representative of the exercises included on this worksheet and related 6.70 Transport Across Membranes Diffusion and Osmosis skill assessments:

Problem 1Difficulty: Mastery
Study the four membrane models. Which model best shows both diffusion and osmosis happening correctly at the same time?
AModel A
BModel B
CModel C
DModel D
Solution & Explanation:Model A is the only one that correctly shows oxygen diffusing down its gradient and water moving by osmosis toward the side with more dissolved sugar while blocked sugar stays in place.
Problem 2Difficulty: Mastery
Which claim about passive transport is best supported by evidence from diffusion and osmosis experiments?
ACells can move materials without using energy when concentration differences already exist
BPassive transport works only for water
CPassive transport always moves materials from low concentration to high concentration
DPassive transport can happen only in artificial membranes
Solution & Explanation:Diffusion and osmosis both show that materials can move down difference in concentrations without ATP.
Problem 3Difficulty: Mastery
A plant cell is placed in fertilizer solution and later heavy rain dilutes the soil around it. Which sequence best describes the likely water movement?
AWater first leaves the cell in the concentrated fertilizer solution, then enters the cell after rain dilutes the soil
BWater first enters the cell, then leaves even more quickly after rain
CWater never moves because the cell wall blocks osmosis
DSalt moves instead of water in both cases
Solution & Explanation:A concentrated fertilizer solution pulls water out at first, but once rain lowers the outside concentration, water can move back into the cell.
