Nucleus Full 3d diagram
Recognising Nucleus Full 3d
Nucleus Full 3d supports Viewing Cells with Light Microscopes and Staining 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.
Syllabus Link
Primary private mapping: OCR GCSE Biology J247, Cell level systems.
Exam Answer Move
The mapped objective is: Communicate the key features of the way light microscopes and staining can be used to view cells. Diagram marks usually come from linking a named structure to what it does.
Barrel Stave diagram
Recognising Barrel Stave
Barrel Stave supports Viewing Cells with Light Microscopes and Staining by giving students a diagram they can connect to the specification point being tested.
What To Explain
The diagram should be used to explain the mapped specification point: Communicate the key features of the way light microscopes and staining can be used to view cells.

The image is useful only when the answer links what is shown to the biological idea in the objective.
Broken Membrane diagram
Recognising Broken Membrane
Broken Membrane supports Viewing Cells with Light Microscopes and Staining by giving students a diagram they can connect to the specification point being tested.
What To Explain
The membrane is selectively permeable, so substances move across it by diffusion, osmosis or active transport depending on the particle and gradient.
