| Bacteria Structure | ||
| #1 | What is the structure used for movement? | Flagellum |
| #2 | What is the genetic material found inside? (Bacteria) | DNA |
| #3 | What is the fluid filled space? | Cytoplasm |
| #4 | What is the main structural difference between eubacteria and archaebacteria? | A peptidoglycan layer |
| #5 | Where are the ribosomes found? | Floating in the cytoplasm |
| Virus Structure | ||
| #1 | What is a bacteriophage? | A virus that infects bacteria |
| #2 | What are the leg looking structures called on the T4 virus? | Tail fiber |
| #3 | What is found in the head of a T4 virus? | DNA |
| #4 | What is a virus's protein coat called? | A capsid |
| #5 | What is a typical virus composed of? | A core of DNA or RNA surrounded by a protein coat |
| Metabolic Diversity | ||
| #1 | Use light energy to convert carbon dioxide and water to carbon compounds | Photoautotrophs |
| #2 | These organisms are photosynthetic, but they also need to take in organic compounds as a carbon source | Photoheterotrophs |
| #3 | These organisms must take in organic material for both energy and a supply of carbon | Chemoheterotrophs |
| #4 | These organisms use energy directly from chemical reastions involving ammonia, hydrogen sulfide, nitrates, etc | Chemoautotrophs |
| #5 | These organisms can live deep in the darkness of the ocean | Chemoautotrophs |
| Bacteria Growth, Reproduction, and Releasing of Energy | ||
| #1 | Exchange of genetic information through a hollow bridge that forms between two bacterial cells | Conjugation |
| #2 | A ____________ is formed when a bacterium produces a thick internal wall that encloses its DNA and a portion of its cytoplasm | Endospore |
| #3 | A group of bacteria that can survive with or without oxygen are known as _________________ ___________________ | facultative anaerobes |
| #4 | A type of asexual reproduction in which an organism replicates it's DNA and divides in half producing two identical daughter cells | Binary Fission |
| #5 | These type of bacteria live in the absense of oxygen | Obligate anaerobes |
| Lytic and Lysogenic Infections | ||
| #1 | What is a host cell? | The bacteria cell used by the virus as a home for its replication process |
| #2 | The type of viral infection that kills the host cell immediately is called ____________ | Lytic |
| #3 | What does a bacteriophage inject once it lands onto a bacteria? | its DNA |
| #4 | What is the basic concept of lysogenic infections? | A host cell makes copies of the virus indefinately because it integrated it's DNA |
| #5 | What happens when the cell lyses? | New bacteriaphages (viruses) get released |
| Final Question | |
| Describe how lytic infection can lead to a spread of viruses throughout an organism | Lytic infection creates hundreds of virus particles that burst out of the cell and leave to infect another bacteria |
