3. OrganelleFunctionsAnalogy nucleus Controls cell activities Contains DNA Your brain Principal’s office @ MTHS Animal CellPlant Cell

4. OrganelleFunctionsAnalogy chromatin/DNA Carries genetic information for traits passed from parents to offspring. Blueprints for building. Cookbook, instruction manual Animal CellPlant Cell

5. OrganelleFunctionsAnalogy cell membrane Outer covering of cell, controls what goes in and out. Your skin Animal CellPlant Cell

6. OrganelleFunctionsAnalogy cell wall Thick outer wall of plant cells. Provides protection and support. Brick wall, Cereal box Animal CellPlant Cell Cell wall Cell membrane

7. OrganelleFunctionsAnalogy cytoplasm Liquid part of cell outside of nucleus. Chemical reactions take place here Water in an aquarium, Air in room, broth in soup Animal CellPlant Cell

8. OrganelleFunctionsAnalogy ribosome Makes proteins factories Animal CellPlant Cell

9. OrganelleFunctionsAnalogy endoplasmic reticulum Pathways for transporting proteins Assembles, modifies proteins and lipids Highways, roads Assembly lines, auto body shop. Animal CellPlant Cell

11. OrganelleFunctionsAnalogy Golgi apparatus Modifies, sorts, & packages proteins for shipping out of cells post office, UPS, Fed Ex Animal CellPlant Cell

13. OrganelleFunctionsAnalogy mitochondria “Powerhouse of cell”, where glucose is broken down to get energy Power plant, electricity generator Animal CellPlant Cell

15. OrganelleFunctionsAnalogy chloroplasts Where photosynthesis happens, where food is made in plant cells. Kitchen, farm, cafeteria Solar panels Animal CellPlant Cell

18. OrganelleFunctionsAnalogy vacuoles Storage bubbles for food, water, waste Closets, refrigerator, warehouses Animal CellPlant Cell

19. OrganelleFunctionsAnalogy lysosomes Hold enzymes used to break down cell parts to build new cells. Recycling centers, trash collectors Animal CellPlant Cell

20. OrganelleFunctionsAnalogy cytoskeleton Network of protein fibers running throughout cell. Provides internal support. Your skeleton, framework for building Animal CellPlant Cell

22. Animal Cell cytoskeleton ribosomes cytoplasm Golgi apparatus mitochondrion Cell membrane Endoplasmic reticulum vacuole nucleus

25. Q: What are cells and why are they important to learn about? Building blocks of living things, what ALL living things are made up of. Helps us better understand how living things work. Helps us understand diseases & find cures.
