3. Organisms can be classified by their cell type
A domain is a broad category of living things based on characteristics of their cells. Three domains:
Archaea: Prokaryotic organisms living in extreme environments.
Bacteria: Prokaryotic organisms
Eukarya: All eukaryotic organisms (plants, animals, fungi, protists)

4. Cells in multicellular organisms specialize
Specialization: specific cells perform specific functions
A single cell from a multicellular organism CANNOT survive on its own
Example: A nerve cell

5. A multicellular organism is a community of cells
In more complex organisms:
Cells are specialized and grouped together
Tissue: a group of similar cells that are organized to do a specific job
Organ: different tissues working together to perform a particular function
Organ System: different organs and tissues working together
Humans have 11 major organ systems
Organism: highest level of organization
