Presentation Transcript

  1. Cell Organelles

  2. Bell Ringer What makes up the cell membrane?

  3. Nucleus

  4. Nucleus • Controls the Cell • Surrounded by a Nuclear Envelope • Contains DNA • Covered by Nuclear Pores

  5. Endoplasmic Reticulum

  6. Endoplasmic Reticulum • An extensive system of internal membranes that move proteins and other substances through the cell • 2 Types • Rough ER • Smooth ER

  7. Rough ER • Covered in Ribosomes • Helps transport the proteins that are made by its attached ribosomes. • Proteins cross the Rough ER Membrane and pinch off to form a vesicle.

  8. Vesicle • Small membrane bound sac that transports substances in cells.

  9. Smooth Endoplasmic Reticulum • Lacks Ribosomes • Smooth ER makes lipids and breaks down toxic substances

  10. Packaging Proteins • Newly packaged proteins move from the ER to the Golgi Apparatus • Golgi Apparatus – set of flattened membrane bound sacs that serve as the packaging and distribution center of the cell • Enzymes inside the golgi modify the proteins, which then are enclosed in new Vesicles that bud from the surface of the golgi apparatus

  11. Golgi Apparatus

  12. Lysosomes • Type of vesicle that contain a cells digestive enzymes • Made by the golgi apparatus and digest worn out particles, bacteria, or viruses found in the cell

  13. Groups! • List and determine the steps of packaging the distribution of proteins

  14. Mitochondria

  15. Mitochondria • Harvests energy from organic compounds to make ATP. • Mitochondria have a large surface area. • A folded inner membrane of the mitochondria is where production of ATP occurs.

  16. Mitochondria • Why would muscle cells contain high amounts of mitochondria?

  17. Plant vs Animal Cell • List three differences between plant and animal cells

  18. Plant • Plant cells have three additional structures than animal cells • 1. Cell Wall • 2. Chloroplasts • 3. Central Vacuole

  19. Cell Wall • Surrounds the cell membrane • Composed of Proteins and Carbohydrates • Helps support and maintain shape of cell • Connects it to adjacent cells

  20. Chloroplasts • Organelles that use light energy to make Carbohydrates from Carbon Dioxide and Water

  21. Central Vacuole • Stores water in the cell • What happens when this is full/empty?

  22. Plant Cell

  23. Animal Cell
