• Whats the function of the nucleus?

  Contains genetic information and controls cell activities
• Whats the function of the cell membrane?

  Controls what can enter and exit the cell
• Whats the function of the cytoplasm?

  site of chemical reactions
• Whats the function of the mitochondria?

  where aerobic respiration takes place
• whats the function of the ribosome?

  site of protein synthesis (where proteins are made)
• whats the function of the cell wall?

  supports the cell (shape, structure, support, protect)
• whats the function of the vacuole?

  contains cell sap
• whats the function of the chloroplast?

  site of photosynthesis

  bacterial cells
• what cell types have a sap vacuole?

  plant and fungal cells
• How many micrometres are in a millimetre?

  1000
