Cell organelles

  1. 1. Cell Organelles What you need to know
  2. 2. An organelle is a membrane-bound structure that carries out specific activities for the cell.
  3. 3. You will need to know the following organelles and their function: <ul><li>Cell Membrane </li></ul><ul><li>Nucleus </li></ul><ul><li>Cytoplasm </li></ul><ul><li>Mitochondria </li></ul><ul><li>Golgi Complex </li></ul><ul><li>Ribosomes </li></ul><ul><li>Smooth Endoplasmic Reticulum </li></ul><ul><li>Rough Endoplasmic Reticulum </li></ul><ul><li>Cell Wall </li></ul><ul><li>Chloroplast </li></ul><ul><li>Central Vacuole </li></ul><ul><li>Lysosome </li></ul>
  4. 4. Cell Membrane <ul><li>Every cell is enclosed by a cell membrane. It controls the passage of materials in and out of the cell. </li></ul>
  5. 5. Nucleus <ul><li>The control center of the cell that contains DNA (chromosomes) and the nucleolus. </li></ul>
  6. 6. Cytoplasm (not an organelle - but important) <ul><li>All organelles reside (live and float around in) the cytoplasm. </li></ul>
  7. 7. Mitochondria <ul><li>This organelle processes energy for a cell. It makes ATP. </li></ul><ul><li>(ATP = energy) </li></ul><ul><li>Involved in cellular respiration. </li></ul>
  8. 8. Golgi Complex <ul><li>The protein packaging and transport center of the cell. </li></ul><ul><li>Has incoming and outgoing vesicles. </li></ul>
  9. 9. Ribosomes <ul><li>Synthesizes proteins. </li></ul><ul><li>Present in the cytoplasm. </li></ul><ul><li>Present with Rough ER. </li></ul><ul><li>No membrane present. </li></ul>
  10. 10. Smooth Endoplasmic Reticulum <ul><li>Transports materials throughout the cell. </li></ul><ul><li>Produces lipids and hormones </li></ul>
  11. 11. Rough Endoplasmic Reticulum <ul><li>Covered with ribosomes. </li></ul><ul><li>Produces proteins. </li></ul><ul><li>Transports materials throughout the cell. </li></ul>
  12. 12. Lysosome <ul><li>Breaks down materials for digestion. </li></ul><ul><li>Contains special enzymes for digestion in the cell. </li></ul>
  13. 13. Cell Wall (Plant Cell Only) <ul><li>Rigid and strong wall. </li></ul><ul><li>Protects and maintains the shape of the cell. </li></ul>
  14. 14. Chloroplast (Plant Cell Only) <ul><li>Contains chlorophyll. </li></ul><ul><li>Makes plants green. </li></ul><ul><li>Uses light energy to make ATP & sugars. </li></ul><ul><li>Photosynthesis takes place here. </li></ul>
  15. 15. Central Vacuole (Plant Cells) <ul><li>Most plant cells have one large one. </li></ul><ul><li>Filled w/ fluid. </li></ul><ul><li>Helps maintains turgor pressure and shape of cell. </li></ul>
