The Endoplasmic Reticulum diagram
Specification Link
This cell structure diagram is used for: 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.
What To Explain
A correct answer links the visible cell structure to its function, such as control, respiration 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. Exam answers need a structure-function link.
