Cells to Organ Systems
Describe the hierarchical organisation of multicellular organisms: cells → tissues → organs → organ systems → organism
Suggested ages 11–12
Evidence of understanding
- Places cells, tissues, organs, and organ systems in the correct order of organisation
- Gives a specific example of each level (e.g. muscle cell → muscle tissue → heart → circulatory system → human)
- Explains why specialised cells are needed in a multicellular organism
Assessment prompt
If Cells to Organ Systems was asked to explain how the body is built up from the smallest parts to the whole, could they describe the levels from individual cells all the way up to organ systems — with a real example at each level?
