Cell specialisation explained
This statement asks you to use supplied information to link a cell's structure to its job at increasing levels of organisation.
Read the full explanation
A tissue is a group of similar cells working together, an organ is several tissues working together, an organ system is several organs working together, and the whole organism is all the systems combined. For example, a sperm cell has a tail for swimming, many mitochondria for energy and an acrosome containing enzymes, so it can reach and fertilise an egg; this contributes to the reproductive system and the whole organism. You should name a structural feature, state its function, and explain how that function helps the cell, tissue, organ, system or organism carry out its role.
Your focus
- Describe structural features of named specialised cells.
- Explain how each feature enables the cell to carry out its function.
- Relate cell specialisation to tissues, organs, organ systems and whole organisms using supplied information.
Cell specialisation exam tips
Marking Points
- Identifies a named cell type and describes at least one structural feature accurately.
- Links each structural feature to a specific function, for example many mitochondria release energy for movement or active transport.
- Places the cell in context by explaining its role in a tissue, organ, organ system or whole organism.
- Uses correct levels of organisation vocabulary, distinguishing cells, tissues, organs, organ systems and organisms.
- Applies information provided in the question rather than relying only on recalled examples.
Examiner Tips
- 💡Use the structure–function sentence pattern: 'The cell has ... which allows it to ... so that ...'.
- 💡When the question supplies information, quote or refer to it directly to show you have used the given context.
- 💡Name the level of organisation explicitly, for example 'in the leaf tissue' or 'in the root hair cell of the root'.
- 💡Check that every clause of the question is addressed, including the level of organisation specified.
Common Mistakes
- Describing a feature without linking it to function; the correction is to state both the feature and the job it performs.
- Confusing an organ with an organ system; the correction is to remember that an organ system contains several organs, such as the digestive system containing the stomach and small intestine.
- Giving a vague function such as 'helps the cell work'; the correction is to name the precise process, such as absorbing water or transmitting electrical impulses.
