Cell Organelles

  1. 1. Chapter 3 Section 2 Cell Organelles Structure and Function
  2. 2. Cell Wall <ul><li>Rigid structure that gives support to the cell. </li></ul><ul><li>Plants,fungi, and algae have cell walls. </li></ul><ul><li>Made of cellulose. </li></ul><ul><li>When the cell wall lacks water the cell droops. </li></ul>
  3. 3. Cell Membrane <ul><li>All cells have cell membrane </li></ul><ul><li>Protective barrier that encloses a cell </li></ul><ul><li>Outermost structure of cells that do not have a cell wall. </li></ul><ul><li>Made of lipids and phospholipids. </li></ul>
  4. 4. Cytoskeleton <ul><li>Web of proteins in the cytoplasm </li></ul><ul><li>Muscle and skeleton </li></ul><ul><li>Helps cells move </li></ul><ul><li>Keeps cell wall/membrane from collapsing </li></ul>
  5. 5. Nucleus <ul><li>“ Brain” of the cell </li></ul><ul><li>All eukaryotic cells have one </li></ul><ul><li>Contains DNA </li></ul><ul><li>Pores allow things to travel from the nucleus to the cytoplasm </li></ul><ul><li>Nucleolus-where cell begins to make its ribosomes. </li></ul>
  6. 6. Ribosomes <ul><li>Make proteins </li></ul><ul><li>More ribosomes than any other organelle. </li></ul><ul><li>Proteins are made of amino acids. </li></ul><ul><li>Found mostly on the rough endoplasmic reticulum. </li></ul>
  7. 7. Endoplasmic Reticulum (ER) <ul><li>Rough and Smooth </li></ul><ul><li>Rough-covered with ribosomes. ER delivers proteins from ribosomes throughout cell. </li></ul><ul><li>Smooth-makes lipids and breaks down toxic materials that could harm the cell. </li></ul>
  8. 8. Mitochondria <ul><li>“ Powerhouse of the Cell” </li></ul><ul><li>Sugar is broken down and energy is released to the cell. </li></ul><ul><li>ATP-energy is stored here and used by the cell to do work </li></ul>
  9. 9. Chloroplasts <ul><li>Photosythesis takes place in the chloroplast </li></ul><ul><li>Green colored due to chlorophyll </li></ul><ul><li>Use sunlight to make sugar and oxygen </li></ul><ul><li>Only found in plant and algae </li></ul>
  10. 10. Golgi Complex <ul><li>Packages and distributes proteins </li></ul><ul><li>Looks like smooth ER </li></ul><ul><li>Lipids and proteins from ER are delivered here. </li></ul><ul><li>Vesicle-sac that surrounds material to be moved into or out of the cell. </li></ul>
  11. 11. Lysosomes <ul><li>“ Suicide Sacs” </li></ul><ul><li>Responsible for digestion </li></ul><ul><li>Found mainly in animal cells </li></ul><ul><li>Enzymes from lysosomes are bumped into vesicles to digest particles. </li></ul>
  12. 12. Vacuole <ul><li>Large vesicle </li></ul><ul><li>Store water and liquids </li></ul><ul><li>Help support the cell </li></ul>
  13. 13. Eukaryotic Animal Cell
  14. 14. Eukaryotic Plant Cell
