|
Active transport moves substances from a more dilute solution to a more concentrated solution (against a concentration gradient). |
|
What is active transport? |
|
|
|
Active transport requires energy from respiration. |
|
Does active transport require energy? |
|
|
|
Active transport allows mineral ions to be absorbed into plant root hairs from very dilute solutions in the soil. |
|
How does active transport allow plants to absorb esstential ions from soil? |
|
|
|
Plants require ions for healthy growth. |
|
Why do plants require ions from the soil? |
|
|
|
Active transport also allows sugar molecules to be absorbed from lower concentrations in the gut into the blood which has a higher sugar concentration. |
|
How does active transport allow sugar to move from the gut into the blood when it has a higher sugar concentration? Venn Diagram to sort conditions between diffusion, osmosis and active transport (passive, uses energy, against concentration gradient, across a membrane, movement of water et.c) |
|
|
|
Sugar molecules are used for cell respiration. |
|
Why is sugar esstential to cells of living things? Describe the exchange that takes place in the small intestine. |
|
|
|
Students should be able to describe how substances are transported into and out of cells by diffusion, osmosis and active transport |
|
What are the three ways that substances can enter and leave cells? Explain why villi cells need a high number of mitochondria / why so much active transport needs to take place in the small intestines. |
|
|
|
students should be able to explain the differences between the three processes. |
|
What are the differences between diffusion, osmosis and active transport? GF: Evaluate whether it is worth the small intestines using energy to actively transport sugar into the blood. |
