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 Membrane 2 5 diagram
Recognising Emptycell Membrane 2 5
Emptycell Membrane 2 5 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.
