Ss Chapter 9

  1. 1. Chapter 9 Cells GEE Science Summer Remediation Mr. Nash Donnie Bickham Middle School Room 204
  2. 2. Origins of Life <ul><li>Two main ideas: </li></ul><ul><ul><li>Creationism </li></ul></ul><ul><ul><li>Evolution </li></ul></ul>Pg.169
  3. 3. Origins of Life <ul><li>Creationism </li></ul><ul><ul><li>Life was created by a greater being or God. </li></ul></ul><ul><ul><li>Because of religious implications not commonly taught in public schools. </li></ul></ul>Pg. 169
  4. 4. Origins of Life <ul><li>Evolution </li></ul><ul><ul><li>All life evolved from the same beginnings of chemicals to cells to organisms. </li></ul></ul>Pg. 169
  5. 5. THE CELL <ul><li>The cell is the structural and functional unit of all organisms. </li></ul><ul><li>Cells have many small structures called organelles. </li></ul><ul><li>Cell Theory states that all living things are made of cells and that all cells come from other living cells of the same kind. </li></ul>Pg. 170
  6. 6. THE CELL <ul><li>There are two basic types of cells. </li></ul><ul><ul><li>Prokaryotic </li></ul></ul><ul><ul><li>Eukaryotic </li></ul></ul>Pg. 170
  7. 7. Prokaryotic Cells <ul><li>Do not have a true nucleus. </li></ul><ul><li>Do not have an organized membrane surrounding the genetic material </li></ul><ul><li>Do not have membrane bound organelles. </li></ul><ul><li>Example: </li></ul><ul><ul><li>Bacteria </li></ul></ul>Pg.170
  8. 8. Eukaryotic Cells <ul><li>Have a true nucleus surrounded by a nuclear membrane. </li></ul><ul><li>Many membrane bound organelles. </li></ul><ul><li>Examples: </li></ul><ul><ul><li>Plant & Animal Cells </li></ul></ul><ul><li>Plant cells contain cell walls and plastids that animal cells do not. </li></ul>Pg170.
  9. 9. Organelles of the Cell <ul><li>Nucleus </li></ul><ul><li>Endoplasmic Reticulum (ER) </li></ul><ul><li>Ribosomes </li></ul><ul><li>Mitochondria </li></ul><ul><li>Plastids </li></ul><ul><ul><li>Plant Cells Only </li></ul></ul><ul><li>Golgi Bodies </li></ul><ul><li>Lysosomes </li></ul><ul><li>Vacuoles </li></ul><ul><li>Microfilaments </li></ul><ul><li>Microtubules </li></ul><ul><li>Cilia & Flagella </li></ul><ul><li>Centrioles </li></ul><ul><ul><li>Animal Cells Only </li></ul></ul><ul><li>Cell Wall </li></ul><ul><li>Cell Membrane </li></ul><ul><li>Cytoplasm </li></ul><ul><li>Nucleolus </li></ul>Pg.171
  10. 10. THE CELL <ul><li>Some organisms are unicellular. </li></ul><ul><ul><li>Meaning they have only one cell. </li></ul></ul><ul><ul><li>Bacteria and Amoebas </li></ul></ul><ul><li>Some organisms are multicellular. </li></ul><ul><ul><li>Meaning they have many cells working together to carry out life. </li></ul></ul>Pg.172
  11. 11. Multicellular Organization <ul><li>Cell </li></ul><ul><li> </li></ul><ul><li>Tissue </li></ul><ul><li> </li></ul><ul><li>Organ </li></ul><ul><li> </li></ul><ul><li>Organ System </li></ul><ul><li> </li></ul><ul><li>Organism </li></ul>Pg. 172
