Simple Mitochondria Network2 diagram
Recognising Simple Mitochondria Network2
Simple Mitochondria Network2 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.

Recognising Simple Mitochondria Network
Simple Mitochondria Network supports Subcellular Structures and Their Functions 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.

This is linked to: Build an explanation of the way the sub-cellular structures of eukaryotic and prokaryotic cells are related to their functions, covering: a animal cells – nucleus, cell membrane, mitochondria and ribosomes b plant cells – nucleus, cell membrane, cell wall, chloroplasts, mitochondria, vacuole and ribosomes c bacteria – chromosomal DNA, plasmid DNA, cell membrane, ribosomes and flagella. A strong answer names the transport process and links it to membrane structure.
