Bacteria and Viruses Review Virus Structure Label the structures and match them to their function (What they do) A. DNA or RNA 1. Helps the virus attach B. Protein Coat or Capsid 2. Instructions a virus carries C. Tail SHeath 3. Protective covering Bacteria Structure Label the structures A. DNA B. Nucleus C. Cell Wall D. Flagellum E. Pili Lytic vs. Lysogenic Cycle Match these letters to the correct steps and cycles A. Lytic Cycle B. Lysogenic Cycle C. Bacteriophage attaches and inserts DNA D. Host cell produces more bacteriophage E. Bacteriophage DNA joins host cell DNA F. Bacteriophage escape by bursting host cell Classifying Bacteria Label the shapes A. Coccus B. Spirilla C. Bacillus Review Questions 1) Unlike Chemoautotrophs, Photoautotrophs get their energy… a) Directly from the sun c) Directly from food molecules b) directly from inorganic molecules d) directly from other organisms 2) The term that is not closely related to the others is a) Eubacteria b) bacteria c) Prokaryote d) Eukaryote Review Questions 3) Certain viruses called _______ viruses cause cancer in animals a) Bacteriophage b) oncogenic c) AIDS c) Prophage 4) Bacteria help the environment by a) Carrying out photosynthesis b) Recycling nutrients c) Nitrogen fixation d) All of the above Review Questions 5) Bacteriophage infect a) Other viruses c) any available host c) bacteria only d) cells undergoing the lytic cycle Answers… Virus Structure B A C Label the structures and match them to their function (What they do) A. DNA or RNA 1. Helps the virus attach B. Protein Coat or Capsid 2. Instructions a virus carries C. Tail SHeath 3. Protective covering Bacteria Structure E C Label the structures A. DNA B. Nucleus C. Cell Wall D. Flagellum E. Pili D A Bacteria don’t have a nucleus and flagella are longer than pili Lytic vs. Lysogenic Cycle Match these letters to the correct steps and cycles C A. Lytic Cycle B. Lysogenic Cycle C. Bacteriophage attaches and inserts DNA A B F D. Host cell produces more bacteriophage E. Bacteriophage DNA joins host cell DNA F. Bacteriophage escape by bursting host cell D E Classifying Bacteria Label the shapes A B C A. Coccus B. Spirilla C. Bacillus Review Questions 1) Unlike Chemoautotrophs, Photoautotrophs get their energy… a) Directly from the sun b) directly from inorganic molecules c) Directly from food molecules d) directly from other organisms Photo means light. Photoautorophs make their own energy from light. How do chemoautotrophs get energy? 2) The term that is not closely related to the others is a) Eubacteria b) bacteria c) Prokaryote d) Eukaryote A, B, and C are all bacteria. A Eukaryote has a true (eu) Nucleus (karyote). Bacteria don’t have a nucleus Review Questions 3) Certain viruses called _______ viruses cause cancer in animals a) Bacteriophage b) oncogenic c) AIDS c) Prophage To cause (gen) cancer (onco)=> onco-genic 4) Bacteria help the environment by a) Carrying out photosynthesis b) Recycling nutrients c) Nitrogen fixation d) All of the above Look back at your notes and homework, these are listed Review Questions 5) Bacteriophage infect a) Other viruses c) any available host c) bacteria only d) cells undergoing the lytic cycle Things to study (Look at your notes and homework) Structures of bacteria and viruses The difference between Lytic and Lysogenic cycle How to classify bacteria – What makes them different from others How do viruses get us sick How are bacteria useful
