Osmosis and Water Potential: Quantitative Analysis and Plant Cell Responses
Students will learn the overall word equation for aerobic respiration and understand that it releases energy from glucose with oxygen.
About This Topic
Students will learn the overall word equation for aerobic respiration and understand that it releases energy from glucose with oxygen.
Key Questions
- Apply water potential equations to predict the direction and magnitude of osmotic water movement and the resulting change in turgor pressure when plant cells with defined solute potentials are placed in solutions of varying osmolarity.
- Analyse how the values of solute potential and pressure potential change as a plant cell progresses from full turgor through incipient plasmolysis to full plasmolysis, and determine the water potential at each state.
- Evaluate the experimental design of a sucrose concentration series experiment for determining the water potential of potato tissue, identifying sources of systematic and random error and proposing modifications to improve precision.
