Golgi apparatus 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.

Intracellular components 16 diagram
Specification Link
This cell structure diagram is used for: Build an explanation of the way the sub-cellular structures of eukaryotic and prokaryotic cells are related to their functions, covering: a animal cells – nucleus, cell membrane, mitochondria and ribosomes b plant cells – nucleus, cell membrane, cell wall, chloroplasts, mitochondria, vacuole and ribosomes c bacteria – chromosomal DNA, plasmid DNA, cell membrane, ribosomes and flagella.

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.
