Passive Transport: Simple Diffusion, Facilitated Diffusion, and Osmosis
Students will investigate the basic structure and function of plants, focusing on their role as producers and their importance to all other life forms.
About This Topic
Students will investigate the basic structure and function of plants, focusing on their role as producers and their importance to all other life forms.
Key Questions
- Differentiate between simple diffusion and facilitated diffusion in terms of mechanism, energy requirement, and saturation kinetics, using the contrast between oxygen diffusion and glucose transport via GLUT transporters as examples.
- Apply water potential equations to predict the direction and magnitude of osmotic water movement between plant cell compartments with defined solute and pressure potentials.
- Analyse data from a plasmolysis experiment to determine the solute potential of a plant cell at incipient plasmolysis and evaluate the assumptions underlying this method.
