Specialised Cells and Their Adaptations
- Build an explanation of the way changes in microscope technology, covering electron microscopy, have enabled us to see cell structures and organelles with more clarity and detail than in the past and increased our understanding of the role of sub-cellular structures.
Microscope Technology and Cellular Understanding
- Show secure understanding of number, size and scale, covering the use of estimations and explain when they should be used.
