Has a membrane bound nucleus and organelles, much more complex
Bacteria
Prokaryotic cells
single celled
have peptidoglycan in the cell membrane
Archaea
Prokaryotic cell
no peptidoglycen in membrane
Similar shape and size as bacteria
Can grow in extreme environments
Eucarya
Eukaryotic cells (one or more cells) Include: Fungi, algae, protozoa, and helminths
Algae
Single or multicellular
Sunlight for energy
Micro or macroscopic
Fungi
Single or multicellular

Micro or macroscopic
Protozoa
Single celled
Organic compounds for energy
Microscopic
