1. Prokaryotes - Single celled organisms - No membrane bound organelles - ex: no nucleus or mitochondria - Free floating DNA - Bacteria are prokaryotic

2. Eukaryotes - Single or multicellular organisms - Much bigger than prokaryotic cells - Have membrane bound organelles - ex: nucleus, mitochondria - DNA is packed tightly in the nucleus - Animals, plants, protists, and fungi are eukaryotic

3. What do prokaryotes and eukaryotes both have in common? Cell membrane Both contain DNA Cytoplasm Ribosomes

4. An organelle (small organ) is a specialized structure inside of the cell. There are many different kinds and all have different functions.

5. Cell Membrane Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: 1.Separates the inside and outside of the cell - Semi-permeable Both

6. Cell Wall Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: Rigid wall that protects the cell Plants Both

7. Cytoskeleton Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: 1.Framework of the cell 2.Made of microtubules (hollow) and microfilaments (solid) Both

8. Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: 1.A gel-like substance that is found inside the cell 2. Organelles float in it Both

9. 1.Controls all activities in the cell 2.Contains DNA Function: Found in animal or plant cells: Both Found in prokaryotes or eukaryotes:Eukaryotes

10. Ribosome Function: Protein Synthesis Found in animal or plant cells: Both Found in prokaryotes or eukaryotes: Both

11. Function: 1.The site of cellular respiration - Makes ATP 2. The powerhouse of the cell Found in animal or plant cells: Both Found in prokaryotes or eukaryotes: Eukaryotes

12. Chloroplast Function: 1.Site of photosynthesis - Makes food Found in animal or plant cells: Plants Found in prokaryotes or eukaryotes: Eukaryotes

13. Endoplasmic Reticulum Smooth ER Function: 1.Lipid Synthesis 2.Regulates Calcium 3.Removes Toxins Rough ER Function: 1.Manufactures proteins and ships them 2.Covered in ribosomes Found in animal or plant cells: Found in prokaryotes or eukaryotes: Both Eukaryotes

14. Function: Packages proteins for export from the cell Golgi Apparatus Found in animal or plant cells: Found in prokaryotes or eukaryotes: Both Eukaryotes

15. Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: Digestive sacs that break down macromolecules Animal Eukaryotes

16. Vacuole Function: 1. Holds excess water, food, or waste 2.Small in animal cells 3.Large in plant cells Found in animal or plant cells: Found in prokaryotes or eukaryotes: Both Eukaryotes

17. Centrioles Function: Found in animal or plant cells: Found in prokaryotes or eukaryotes: 1.Assist in cell division 2.Found in the nucleus Animals Eukaryotes
