Key Terms:
Atom
Molecule
Organelle
Cell
Tissue
Organ
Organ System
Organism
Step-by-Step Guidance
Start by identifying the smallest unit: atoms, which are the basic building blocks of matter.
Next, recognize that atoms combine to form molecules.
Molecules can form organelles, which are specialized structures within cells.
Cells are the basic unit of life and contain organelles.
Groups of similar cells form tissues.
Tissues combine to make organs, which perform specific functions.
Organs work together in organ systems.
The highest level is the organism, which is the complete living being.
