  1. Cell Organelles Unit 2: Cells

  2. Let’s Review! • Two cell types

  3. Prokaryotes - Bacteria

  4. Eukaryotes Nucleus

  5. Two Types of Eukaryotic Cells

  6. Cell Organelles • Organelle = “little organs” • Found only in • Many are “membrane-bound”(a membrane surrounds the organelle) • Cytosol: watery matrix that organelles float in • Cytoplasm: Everything in a cell except the nucleus

  7. Cell Membrane • Functions: • Factory Part: • Found in:

  8. Nucleus • Stores DNA (chromosomes) • Surrounded by the nuclear membrane • Pores let material in and out • Also contains the Nucleolus, which makes ribosomes • Factory Part: • Found in:

  9. Ribosome • Smallest organelle • NOT surrounded by a membrane • Two Types: • Factory Part: • Machines • Found in:

  10. Endoplasmic Reticulum • Functions: • Two Types: • Factory Part: • Found in:

  11. Golgi Apparatus • Function: • Factory Part: • Found in:

  12. Lysosomes • Functions: • Factory Part: • Found in:

  13. Mitochondria • Functions: • Factory Part: • Found in: Sugar + Oxygen Carbon dioxide + Water + ATP ATP = Adenosine triphosphate

  14. Chloroplast • Function: • Factory Part: • Found in: Sunlight + Carbon Dioxide + Water Sugar + Oxygen

  15. Cell Wall • Function: • Factory Part: • Found in:

  16. Vacuoles • Functions: • Factory Part: • Found in:

  17. Cell City Analogy • Cell OrganellesCity Analogies • Cell Membrane City border • Cell Wall City Wall • Cytoplasm Lawns • Endoplasmic Reticulum Highway or road system • Ribosomes Lumber or brick yard • Golgi Bodies Post Office or UPS • Chloroplasts Solar Energy Plants • Nuclear Membrane City Hall Fence with security guard • Mitochondria Energy Plants • Nucleus City Hall • DNA Original Blueprints or the city • RNA Copies of Blueprints • Nucleolus Copy Machine • Lysosomes Waste Disposal/ Recyclers • Vacuole Warehouses, water towers or garbage dumps • Protoplasm Air or atmosphere • Chromosomes Rolled up blueprints • Proteins Lumber or bricks
