Cells to Organ Systems
CONCEPTUALDescribe the hierarchical organisation of multicellular organisms: cells → tissues → organs → organ systems → organism
Mastery Evidence
- 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 [child] 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?”

Show full prerequisite tree
- Plant Cells vs Animal Cells hard
The cell-to-organism hierarchy builds on understanding that different cell types exist
- Parts of Plant and Animal Cells hard
Comparing plant and animal cells requires knowing the components found in each
- Cells Under the Microscope hard
Understanding cell components requires first knowing that cells are the fundamental unit of life
