Presentation Transcript

  1. Which Cells Do and Do Not Have Walls? (1.)

  2. DoDon’t • All Prokaryotes >Achaea and Bacteria • Some Protists • Plants • Fungi • Animals • Most Protists

  3. Under the Microscope Cell wall (6.)

  4. Cell wall purposes Protection Strength Shape maintenance Regulation: Prevents lysis (bursting)

  5. Plasmodesmata • Narrow channels transport: • Water • Nutrients • Director of plant growth and development

  6. Cell Wall Structure

  7. Archaea Inorganic Compounds? Proteins Diversity Polysaccharides

  8. Bacteria! Peptidoglycan Gram-positive vs. Gram-negative (2.) (2.)

  9. Cellulose PLANT CELLS • Primary Wall • Middle Lamella • Secondary Wall >Protists and Plants< (3.) (4.)

  10. CHITIN Fungi

  11. How do cell walls help us? • Paper • Wood • Fiber • Energy • Shelter
