Lipid Yellowgray diagram
Recognising Lipid Yellowgray
Lipid Yellowgray 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.
Membrane 2d Bluelight diagram
Recognising Membrane 2d Bluelight
Membrane 2d Bluelight 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.
