Practise identifying cells and organelles in electron micrographs using labels, visible structures and functional clues from the image.

How this is tested

  • identify labelled organelles such as nucleus, Golgi apparatus, mitochondrion and ER
  • interpret micrograph evidence to name a cell type, such as a secretory or goblet cell
  • link labelled structures to functions, including photosynthesis in chloroplasts
