Cell Theory says that….
1. All living things are made of cells.
2. Cells are the building blocks of all living things.
3. New cells are only made from existing cells.
Cells are the basic units of structure and function in all living
things

Prokaryote Cell
A simple single celled
organism.
•
•
•
•
Do not have a nucleus
Few organelles
Less complicated
All bacteria
• Archaebacteria- oldest and in
harsh conditions
• Eubacteria- Found everywhere
Eukaryote Cell
A more complex cell.
• Have a nucleus
• Many organelles and more complex
• Can be single celled (just on cell) or
multi-cellular
• All plants, animals, fungi, and protists
are eukaryotic cells
• Both have DNA a cytoplasm
and a cell membrane
• Both are microscopic
No Nucleus
Free floating within the cell
Bacteria ( Archaebacteria & Eubacteria)
Unicellular
Yes
Inside the nucleus
Plant, animal, fungi, and protists
Both, mostly Multicellular
