Presentation Transcript

  1. Cell Organelles How does a cell do its job? What is the relationship between a cell and its organelles?

  2. What jobs do cells do? • Some examples: • Making proteins, like keratin (hair follicles) • Sending signals (nerve cells) • Turning sunlight into glucose (leaf cells) • Contracting for movement (muscle cells)

  3. Organelles Cooperate Organelles work together to allow the cell to accomplish its job.

  4. The Nucleus • Controls the cell by giving directions to make proteins, especially enzymes. • It also contains DNA and copies its genetic material so that when the cell divides, the new cell is exactly the same as the original.

  5. Ribosomes • Ribosomes are the site of protein production. • Located on the endoplasmic reticulum

  6. Endoplasmic Reticulum (ER) • A system of folded membranes that transport proteins within the cell

  7. Golgi Complex • G.A. tags proteins and exports them outside the cell in membrane bubbles called vesicles.

  8. Lysosomes • Membranous sac filled with enzymes (certain type of protein) that break down used organelles and large molecules

  9. Vacuoles • Vacuoles are sacs that store water and other materials • Vacuoles are in plant cells.

  10. Chloroplasts • Capture the sun’s energy to make glucose in plants and algae. The energy is stored in chemical bonds.

  11. Mitochondria • Bonds are broken in molecules of glucose to release energy which is stored or used as ATP.

  12. Cell Membrane • Regulates what enters and leaves the cell.

  13. Cell wall • The cell wall provides support to plant cells and bacteria.

  14. Cytoplasm • The region between the cell membrane and the nucleus.

  15. Self Assessment • Level 1=I have never seen this word • Level2=I think I have seen this word, but I don’t know what it means. • Level 3=I have seen this word and it has something to do with… • Level 4= I know this word. I can use it in my speaking, reading, writing, and listening.

  16. Exit Slip • Pick one organelle of the cell. What might happen to the cell if you were to take that organelle away.
