  1. Biology from smallest to biggest
    • atoms
    • molecules
    • organelles
    • cell
    • tissue
    • organ
    • organ systems eg. nervous system
    • organism
    • population
    • ecosystem
  2. Unicellular Organisms
    classes and examples
    • Single cell
    • bacteria (monera)
    • protista/ protozoans
    • some fungi
    • eg. euglena, amoeba
  3. Multicellular
    • made of many cells (often specialized) *all start from stem cell
    • eg. plants, animals, some fungi
  4. What is Differentiation and how does it work?
    • specialization (has unique task)
    • does so by turning certain genes on and off.
  5. Specialized Animal Cells
    • muscle cells
    • red blood cells
    • cheek cells
  6. Specialized Plant cells
    • guard cells
    • xylem cells
    • pollen
  7. Cell Info
    • Typical cell is 5-50 micrometers long
    • Largest single cell -the egg
    • smallest single cell (human) -sperm
  8. Basic Cell Anatomy
    All Cells...
    • are contained by cell membrane
    • have genetic material
    • have cytoplasm with organelles
  9. Organelles...
    • specialized structures in cells
    • specific jobs, various tasks
    • very small
    • found in cytoplasm
    • may or may not be membrane bound
  10. Cells are classified as Prokaryotic or Eukaryotic.
    Prokaryotic is...
    • simple structure
    • no membrane bound nucleas or organelles
    • * nucleoid region (within cell containing genetic material)
  11. Eukaryotic Cells...
    have a membrane bound nucleas and organelles
