Eukaryote vs prokaryote cells
- 1. Two types of Cells: Prokaryote and Eukaryote
- 2. Characteristics of Prokaryote cells Prokaryote cells are small and simple •Very small, about 3 •Only Single-celled (unicellular) organisms mm
- 3. Prokaryote cells outer layer • capsule: slimy outer coating • cell wall: tougher middle layer • cell membrane: delicate inner skin • pili: for sticking to things • flagella: Some have, used to move
- 4. Prokaryote cells have a simple cellular organization: • cytoplasm: inner liquid filling • DNA in one big loop in the cytoplasm • Ribosomes suspended in cytoplasm
- 5. Types of Prokaryotic Cells • Bacteria • Archaea
- 6. A cell is Eukaryotic if… it contain a membrane-bound nucleus with genetic material.
- 7. Characteristics of Eukaryotic Cells • Larger, around 20 mm • Can be multicellular or unicellular
- 8. Eukaryotic cells characteristics • Has a plasma membrane surrounding cytoplasm • Has membrane bound organelles • Has membrane bound, linear, DNA
- 9. Types of Eukaryotic cells •Plant •Animal •Protists •Fungi
- 10. Glow in the dark squid… how does it do that?
Editor's Notes
- Micrometers in size, Eukaryotes are about 7x bigger!
- Ex: E. coli. Have students write this as a couple of sentences in their comparison routine. Sample: Prokaryote cells have a slimy outer coating surrounding a tough cell wall, and finally a delicate cell membrane. They also have structures on their outer body, such as pili and flagella, to help them to move and stick to things.
- Concept: Cellular organization. Put into a sentence or two. Inside the cell membrane, prokaryote cells have cytoplasm, a big loop of DNA and ribosomes.
- Protist - alga
- Protists – algae, animal like – Motile, Fungus-like “Decomposers” from spores and filaments

- Vibrio fischeri, glow in the dark bacteria, help it survive in the ocean. This bacteria “prokaryote” lives in fish and other marine life. Can you think of other mammals or animals that have bacteria in them?
