- 3. Our ObjectivesUpon completingthis lesson you will:Know the names of the basic parts, or organelles, of a cellKnow the functions of all the basic organellesDraw or write out your own model or metaphor to demonstrate the parts of a cell
- 4. Think Back toLast ClassA cell is the basic structural and functional unit of all living thingsEukaryotic& ProkaryoticAnimal & PlantHow cells fit into the rest of the body’s organizationTissueCellOrganOrgan SystemOrganism
- 5. Cell MembraneProvides supportand protectionFunctions as cellThink of our school’s doors and intercom systemand
- 6. CytoplasmJelly-like material thatfills the cellContains water and food for cellHolds organelles in placeThink of the air that fills up this entire school
- 7. NucleusContains DNA, whichmakes you who you areDirects the activity of the cell – for example, when itgrowsand d i v i d e sThink of the principal’s office as the nucleus and the student files in the office as DNA
- 8. Endoplasmic Reticulum (E.R.)The“highway” of the cell that moves materials around to other parts Some parts of the E.R. contain ribosomes, which create proteinsThink of the school hallways where students and teachers transport ideas to other parts of the schoolIf you drive too fast, you’ll end up in the E.R.!
- 9. Golgi ApparatusPackages, stores,and secretes energy for the cell Think of the lunch faculty who bring cafeteria food into the school, then pack and store it in the kitchen for later use
- 10. MitochondriaBreak down foodand release energy to cell – the “Powerhouse” of the cellThink of lunch time at school – food is taken out of packages, cooked, and then provided to students and teachers to power them for the rest of the day
- 11. LysosomesClean up thecell waste products (Lysosomes clean just like Lysol!)Think of the janitors who clean up any waste in the school at the end of the day
