Hierarchy of Organisms

SC.6.L.14.1 - Describe and identify patterns in the hierarchical organization of organisms from atoms to molecules and cells to tissues to organs to organ systems to organisms. 

Cells to Tissues

• organs form organ systems

• organ systems form organisms

Atoms

Atoms are the smallest units of matter (living or not)

Tissues

Cells make up tissues. Two or more tissues make an organ.
