Presentation Transcript

  1. Virus and Bacteria What are Microorganisms?

  2. Cells Prokaryotic Cells Eukaryotic Cells One or many celled organisms Nucleus with membrane Body cell • No Nucleus • No membrane bound organelles • Single celled: • Archaea/bacteria

  3. Characteristics of Bacteria • Prokaryotes • Many are consumers • Some are consumers , decomposers or producers • Single celled • Round, spiral or rod shaped

  4. How Bacteria reproduce Binary Fission • Step 1: genetic information is copied • Step 2: cell membrane begins to split • Step 3: new cell wall is formed • Step 4: Two identical bacteria cells are formed. • Asexual reproduction

  5. exchanging DNA Conjugation During conjugation a plasmid is transferred from one bacteria to another

  6. Characteristics Viruses • Non-living can not replicate on its own • Made of protein coat and genetic material • Protein coat gives virus its shape • Smaller than bacteria • Do Not perform any life functions • Can only replicate inside a cell

  7. Virus Replication
