  • You need to be able to list organelles of plant and animal cells and know which organelles are in plant cells but not in animal cells.

  • Be able to simply describe the function of each organelle

  • You are expected to know more detail than you did in KS3 - know where mitochondria are found and what their function is for example

  • Know that bacteria have DNA loose in the cytoplasm too, as they have no nucleus.

You will need to be able to explain how cells are specialised for a specific function.


Stomata are found in the underside surface of leaves.

Explain how stomata are specialised to assist in the role of transpiration (1) and photosynthesis(1)

Muscle cells have a great many mitochondra. Explain why this is a good adaptation.
