Active transport teaching resources
Worksheets and lesson ideas to challenge students aged 11 to 16 to think hard about active transport (GCSE and Key Stage 3)
Where to start?
Introduce the problem of a sad, lonely plant that has been left on the window ledge in a pot. The concentration of magnesium ions in the soil is now lower than inside the root hair cells. But the plant still needs magnesium ions. What happens next?
Active transport in waterlogged soil
GCSE activity on active transport in waterlogged soil. Students think through the problem of why plants grown in waterlogged soil show nitrogen deficiency. They apply their knowledge to figure out that water displaces oxygen from the soil. As such, aerobic respiration cannot take place, which means no ATP (energy) is available for active transport. This problem also links to the concepts of leaching and denitrification. This is a great thinking problem as it links together many important concepts in biology. (PDF)
- Compare and contrast active transport with osmosis.
- Why might plants treated with cyanide have yellow leaves?
- Compare and contrast active transport with enzyme action, include the importance of shape in both processes.
