The Cell

  1. 1. The cell Learning objective: Compare The structure of Prokaryotic cell and Eukaryotic cell The cell
  2. 2. <ul><li>All living things are made up of cells. </li></ul><ul><li>The cell is the basic unit of life. Based on the organization of their cellular structures, all living cells can be divided into two groups: prokaryotic and eukaryotic. </li></ul><ul><li>Animals, plants, fungi, protozoans, and algae all possess eukaryotic cell types . Only bacteria have prokaryotic cell types . </li></ul>
  3. 3. evolutionary relationships between bacteria, archaea, and the four kingdoms of eukaryotic organisms.
  4. 4. Prokaryotic Cell
  5. 5. <ul><li>Prokaryotes / Prokaryotic </li></ul><ul><li>First organisms, simple structure </li></ul><ul><li>Generally smaller than eukaryotic </li></ul><ul><li>Has one circular chromosome which floats in cytoplasm </li></ul><ul><li>Has no membrane bound organelles </li></ul><ul><li>Can have slime layer / pili / capsule </li></ul><ul><li>Bacteria and some protists </li></ul>
  6. 6. Eukaryotic cell (Plant & animal cell)
  7. 7. <ul><li>Eukaryotes / Eukaryotic </li></ul><ul><li>More evolved, complex cells </li></ul><ul><li>Generally larger than prokaryotic </li></ul><ul><li>Has two or more chromosomes </li></ul><ul><li>Has some membrane bound organelles </li></ul><ul><li>Has mitochondria </li></ul><ul><li>Some protists, most fungi, most plants, and all animals </li></ul>
  8. 8. Summary
  9. 9. Mitotic or meiotic By fission or budding Cell division Present Absent Cell Organelles Present Absent Nucleolus More than one linear Single circular Chromosome Surrounded by a nuclear membrane Not surrounded by nuclear membrane Nuclear region Generally large (5-100m) Generally small (1-10m) Size Eukaryotic cell Prokaryotic cell Parameter
  10. 10. Eukaryotic cell and Prokaryotic cell
