Step 13 of 18 · Cells and classification · SC4-CLS-01
Specialised cells
Each cell is built for its job: the shape tells you the function.
Learn it
Relate the structure of specialised cells to their function, and describe levels of organisation
Idea 1 of 4
Structure fits function
A nerve cell is long, to carry messages a long way, and branched, to connect to many cells. A red blood cell has no nucleus, to make room for haemoglobin. The exam question is always: 'how does its structure help its function?'

Which cell is built like this?
0/0Long and thin, packed with mitochondria and special proteins.
The pattern for every answer
Describe the structure → say the function → relate the two with “so”.
A full-marks answer
Explain how a root hair cell is adapted for its function.
