  2. What is a Cell? • Make up living things • Carry out activities that keep them alive

  3. What is a Cell Wall? • Protected layer • Found on the outside of plasma membrane • If you put a balloon in a box, the box serves a cell wall protecting the balloon

  4. 3 Layers • Middle Lamella- first layer formed, composed of peptic compounds and protein • Primary Wall- second layer formed • Secondary Wall- last layer, is extremely rigid, provides compression strength

  5. Where is the Cell wall found? • Plants • bacteria • Achaea • fungi • algae • Different types of cell wall for each

  6. Cell Wall in Plants, Archaea,, bacteria, • Plants • Primary Walls • Secondary walls • Archaea • Composed of a S-Layer and lack peptidoglycan • Bacteria • Composed of disaccharides and amino acids

  7. What are Cell walls Made of? • Plant cell wall - cellulose • Bacterial cell wall- peptidoglycan • Fungi cell wall- chitin and other polysaccharodes • Archaea cell wall- isoprenyl ether • Algae cell wall- cellulose

  8. Its Function? • Gives it a shape • Protect cell • Acts as a pressure vessel • Prevent over expansion when water enters the cell
