Emptycell Squarerounded diagram
Recognising Emptycell Squarerounded
Emptycell Squarerounded 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.
Syllabus Link
Primary private mapping: OCR GCSE Biology J247, Cell level systems.
Exam Answer Move
The image is useful only when the answer links what is shown to the biological idea in the objective.
Emptycell Quarteroval Membrane Red diagram
Recognising Emptycell Quarteroval Membrane Red
Emptycell Quarteroval Membrane Red 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.

Emptycell Vacuole (11) diagram
Recognising Emptycell Vacuole (11)
Emptycell Vacuole (11) 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.
