Presentation Transcript

  1. Cells Theory, Types, Organelles, and Structure as related to Function

  2. Theory • The Wacky Cell Theory • So, the Cell Theory states: • All organisms are made of cells • All existing cells are produced by other living cells • The cell is the most basic unit of life

  3. Contributors Schleiden • Hook Schwann Leewenhoek Hooke- the 1st to identify and name cells Leewenhoek- made better lenses so was able to see cells in greater detail Schleiden-found that plants are made of cells Schwann- concluded that all living things are made of cells Virchow- proposed that all cells come from other cells Virchow

  4. Cells • Prokaryotic Cells

  5. Cells • Prokaryotic cells do NOT have a nucleus or other membrane-bound organelles. The DNA is suspended in the cytoplasm. All prokaryotes are microscopic single cell organisms.

  6. Cells • Eukaryotic Cells

  7. Cells • Eukaryotic Cells have a nucleus and other membrane-bound organelles. The nucleus is the largest organelle and encloses the genetic information. Eukaryotes may be multicellular or single celled organisms.

  8. Graphic Organizer • You make it…..NOW. • Move over to the lab tables • find a spot and • make a graphic organizer according to your notes • Use the “butcher” paper provided • Put your name, date, class period at the top.

  9. Graphic Organizer

  10. Organelles cytoskeleton nucleusvesicle Endoplasmic reticulumribosomecentriole Golgi apparatus mitochondrion Lysosomecell wallchloroplast vacuole

  11. Cytoskeleton • You and your partners will add this information on all the organelles in class and the best of the PP slides will be posted here.

  12. Cells in Comparison • How SMALL is a cell anyway?

  13. Why are cells so ….well…. small?
