Membrane 2d Bluered diagram
Recognising Membrane 2d Bluered
Membrane 2d Bluered supports Microscope Technology and Cellular Understanding 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.

Primary private mapping: EDEXCEL GCSE Biology 1BI0, Key concepts in biology.
Exam Answer Move
This is linked to: 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. A strong answer names the transport process and links it to membrane structure.
Lipid Yellowgray diagram
Recognising Lipid Yellowgray
Lipid Yellowgray supports Microscope Technology and Cellular Understanding 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.

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. Diagram marks usually come from linking a named structure to what it does.
