  3. 3. UNI CELLULAR ORGANISMS <ul><li>CELL = ORGANISM </li></ul><ul><li>No levels </li></ul><ul><li>Each type of cell is different organism. </li></ul>
  4. 4. MULTI CELLULAR ORGANISMS <ul><li>Cells - Tissue - Organ - System - Organism </li></ul><ul><li>Different types of cells are needed to create different levels. </li></ul>
  5. 5. SPECIALIZATION <ul><li>In MultiCellular organisms, Cells differ from one another for different jobs. </li></ul><ul><li>In UniCellualr organisms- only one cell. </li></ul>

  7. 8. TISSUE <ul><li>CONNECTIVE </li></ul><ul><li>Connects other tissues together. </li></ul><ul><li>ie: Fat, cartilage, bones, blood, ligaments and tendons. </li></ul><ul><li>EPITHELIAL </li></ul><ul><li>Covers the surface of your body and lines the inside of organs. </li></ul>
  8. 9. TISSUE <ul><li>MUSCLE </li></ul><ul><li>Movement of the body’s functions. </li></ul><ul><li>ie: voluntary & involuntary. </li></ul><ul><li>NERVOUS </li></ul><ul><li>Controls & coordinates all body functions. </li></ul><ul><li>ie: brain, nerves </li></ul>
  9. 10. 4 KINDS of TISSUE <ul><li>(group of same cells) </li></ul>
  10. 11. WHAT TYPE OF TISSUE?
  11. 12. ORGAN <ul><li>Different tissue types working together with specific job. </li></ul><ul><li>ie: stomach </li></ul>
