Cell Function

How do cells coordinate activities within their internal environment and the external environment?

Inquiry Question


  • Investigate the way in which materials can move into and out of cells, including but not limited to:
    • Conducting a practical investigation modelling diffusion and osmosis
    • Examining the roles of active transport, endocytosis and exocytosis
    • Relating the exchange of materials across membranes to the surface-area-to-volume ratio, concentration gradients and characteristics of the materials being exchanged
  • Investigate cell requirements, including but not limited to:
    • Suitable forms of energy, including light energy and chemical energy in complex molecules
    • Matter, including gases, simple nutrients and ions
    • Removal of wastes
  • Investigate the biochemical processes of photosynthesis, cell respiration and the removal of cellular products and wastes in eukaryotic cells
  • Conduct a practical investigation to model the action of enzymes in cells
  • Investigate the effects of the environment on enzyme activity through the collection of primary or secondary data
