Proteins (1) diagram
Specification Link
This cell structure diagram is used for: 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.
What To Explain
A correct answer links the visible cell structure to its function, such as control, respiration or protein synthesis.
Exam Answer Move
The mapped objective is: 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. Exam answers need a structure-function link.
Proteins (3) diagram

Brain sections (2) Thalamus Caudate nucleus Putamen Globus pallidus Hippocampus diagram
Specification Link
This nervous system diagram is used for: 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.
What To Explain
Information is passed through the nervous system so the body can coordinate a response.
Exam Answer Move
The mapped objective is: 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. The answer should connect structures such as receptors, neurones, synapses or effectors to coordination and response.
Mitochondria diagram
Recognising Mitochondria
Mitochondria supports Microscope Technology and Cellular Understanding by giving students a diagram they can connect to the specification point being tested.
What To Explain
The answer should name the cell structure and link it to its function, such as control, respiration, photosynthesis or protein synthesis.

Exam Answer Move
The mapped objective is: 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. Diagram marks usually come from linking a named structure to what it does.
