Cell Theory All living things are made of one or more cells. Cells are the basic units of structure and function in organisms. All cells come from existing cells.

Eukaryotic Cells Prokaryotic Cells animals, plants, fungi, & protista (have a nucleus) Prokaryotic Cells Bacteria & Archea such as E coli (no nucleus)

Nucleus Stores the cell’s DNA Round shaped Usually in the center of a cell

Eukaryotes An organism made up of cells that have a nucleus Eukaryotes include animals, plants, protists and fungi but not bacteria.

Eukaryotic Cells

Prokaryotes an organism that consists of a single cell that does not have a nucleus or cell organelles Prokaryotes include bacteria such as E. coli, tuberculosis, or staphylococcus

Prokaryotic Cells

Eu-Do Pro-no A TRICK TO REMEMBER! Eukaryote-Do have a nucleus Prokaryote-no nucleus

Unicellular organisms Unicellular means “one cell”

Multicellular? Multi-cellular means “many cells”
