Cell organelles

  1. 1. Cell Membrane <ul><li>Outer boundary of cell </li></ul><ul><li>Protects the cell </li></ul><ul><li>Controls what enters and leaves the cell </li></ul>
  2. 2. Cell Wall <ul><li>Only found in plant cells </li></ul><ul><li>Adds protection and support </li></ul><ul><li>Made of cellulose. </li></ul><ul><li>Allows water and dissolved substances to pass through. </li></ul>
  3. 3. The Nucleus <ul><li>Controls most activities in the cell </li></ul><ul><li>Contains all genetic information in the form of DNA. </li></ul>
  4. 4. Cytoplasm <ul><li>Clear fluid within cell that contains all organelles </li></ul><ul><li>Moves materials throughout the cell </li></ul>
  5. 5. Endoplasmic Reticulum <ul><li>Series of folded membranes that form sacs or tubes </li></ul><ul><li>Rough ER has ribosomes attached </li></ul>
  6. 6. Ribosomes <ul><li>Transports materials between the cytoplasm and nucleus </li></ul><ul><li>Makes proteins in the cell </li></ul><ul><li>May be free in cytoplasm or attached to ER </li></ul><ul><li>Proteins are vital to life- all cells must produce them </li></ul>
  7. 7. Golgi Bodies <ul><li>Saclike membranes used for storing/ packaging of chemicals </li></ul><ul><li>Cells that make saliva or mucus have many Golgi bodies </li></ul>
  8. 8. Mitochondria <ul><li>Energy producers </li></ul><ul><li>Powerhouse of the cell </li></ul><ul><li>Sausage-shaped </li></ul><ul><li>Many mitochondria in muscle cells </li></ul>
  9. 9. Plastids <ul><li>Only found in plants/ algae </li></ul><ul><li>Contain food or pigments </li></ul><ul><li>Leucoplasts store food </li></ul><ul><li>Chloroplasts contain the pigment chlorophyll </li></ul>
  10. 10. Vacuoles <ul><li>Store food, water, or waste materials </li></ul><ul><li>Plant cells have large vacuoles </li></ul>
  11. 11. Lysosomes <ul><li>Found in Golgi bodies </li></ul><ul><li>Contain digestive enzymes to digest unwanted particles </li></ul><ul><li>Help white blood cells to destroy bacteria </li></ul>
