Name______________________________________ Block____________ From Bacteria to Plants: Chapter 2 Viruses and Bacteria Section 1 Viruses Key Terms: virus host parasite bacteriophage 1. ____________________ an organism that provides a source of energy or a suitable environment for a virus or another organism to live 2. ____________________ a tiny, non-living particle that invades and then reproduces inside a living cell 3. ____________________ a virus that infects bacteria 4. ____________________ an organism that lives on or in a host and causes harm to the host Key Concepts: How do viruses differ from living things? ____________________________________________________ ____________________________________________________ ____________________________________________________ What is the basic structure of a virus? ____________________________________________________ ____________________________________________________ ____________________________________________________ How do viruses multiply? ____________________________________________________ ____________________________________________________ ____________________________________________________ Name______________________________________ Block____________ From Bacteria to Plants: Chapter 2 Viruses and Bacteria Section 2 Bacteria Key Terms: bacteria cytoplasm asexual reproduction ribosome flagellum sexual reproduction respiration endospore binary fission pasteurization conjugation decomposer 1. ____________________ an organism that breaks down chemicals from dead organisms and returns important materials to the soil and water 2. ____________________ a reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents 3. ____________________ singe-celled organisms that lack a nucleus; prokaryotes 4. ____________________ a small, rounded, thick-walled, resting cell that forms inside a bacterial cell 5. ____________________ a long, whiplike structure that helps a cell to move 6. ____________________ a tiny structure located in the cytoplasm of a cell where proteins are Produced 7. ____________________ the region of a cell located inside the cell membrane (in prokaryotes) or between the cell membrane and nucleus (in eukaryotes); contains a gel-like material and cell structures 8. ____________________ a process of heating food to a temperature that is high enough to kill most harmful bacteria without changing the taste of the food 9. ____________________ a reproductive process that involves only one parent and produces offspring that are identical to the parent 10. ___________________ the process in which a unicellular organism transfers some of its genetic material to another unicellular organism 11. ___________________ the process of breaking down food to release its energy 12. ___________________ a form of asexual reproduction in which one cell divides to form two identical cells Key Concepts: How do the cells of bacteria differ from those of eukaryotes? ____________________________________________________ ____________________________________________________ ____________________________________________________ What do bacteria need to survive? ____________________________________________________ ____________________________________________________ ____________________________________________________ Under what conditions do bacteria thrive and reproduce? ____________________________________________________ ____________________________________________________ ____________________________________________________ What positive roles do bacteria play in people’s lives?
