Cells to Organ Systems
Describe the hierarchical organisation of multicellular organisms: cells → tissues → organs → organ systems → organism

Teaching Table
Set out your lesson
Arrange levels of organisation and explain why an organ contains more than one tissue.
Can discuss the supplied example in an accessible mode; adapt directions without supplying the target answer.
Check the learner can follow the model with support before moving on. Source prerequisite ordering is not learner mastery; return to prerequisite work when needed.
Use the supplied labelled cards; no real tissues or microscope required. Open S first, G together, then T alone; put S and G away before T. Keys stay adult-only. No purchase or printing is required; an unavailable physical observation remains pending, not passed.
Materials are ready in each step. Use them on screen or print just the current step. Put teaching examples aside before the learner tries.
What this lesson covers and its limits
These are bounded opportunities, not learner attainment. Partial and blocked source requirements remain so.
- partial: Describe the hierarchical organisation of multicellular organisms: cells → tissues → organs → organ systems → organism
Two hierarchies offered; cellular specialisation across all body systems is not assessed.
- partial: Places cells, tissues, organs, and organ systems in the correct order of organisation
Two hierarchies offered; cellular specialisation across all body systems is not assessed.
- partial: Gives a specific example of each level (e.g. muscle cell → muscle tissue → heart → circulatory system → human)
Two hierarchies offered; cellular specialisation across all body systems is not assessed.
- partial: Explains why specialised cells are needed in a multicellular organism
Two hierarchies offered; cellular specialisation across all body systems is not assessed.
- partial: If {{name}} 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?
