It needs a host to reproduce. What is in the inner core of a virus? genetic material What is the best treatment for a virus? bed rest and plenty of fluids How are bacteria classified ( what type of cell do they have)? prokaryote ____________ bacteria obtain food by consuming autotrophs and heterotrophs. Heterotrophic Genetic material is passed from one bacterium to another across a thread-like bridge during _____________. conjugation During _______ ______ a parent cell copies its genetic material and splits in half to create 2 new cells that look exactly like the parent cel. binary fission Name 4 ways that bacteria move. flagellum, water, air, other organisms, and other objects A protist is classified as a __________. eukaryote Animal-like protists are commonly called _______. protozoans What are plant-like protists commonly called? algae What animal-like characteristic does a euglena have? HINT: food source They can be heterotrophs. What plant-like characteristic does a euglena have? HINT: food source They can be autotrophs. Who was the scientist that first put organisms into groups according to where they lived and whether or not they had blood? Aristotle Who was the “father of taxonomy”? Linnaeus Which group of organisms includes only multicellular heterotrophs? a. plants b. animals c. protists d. bacteria b. animals True of False: The more levels of classification that two organisms share, the less they have in common. false List the major levels of classification from the highest level to the lowest level. Domain Kingdom Phylum Class Order Family Genus Species The mistaken idea that life can come from no life is Spontaneous generation What scientist did a meat and maggots experiment to try and disprove spontaneous generation? Redi What scientist finally disproved spontaneous generation with a chicken broth experiment? Pasteur The maintenance of stable internal conditions despite the outside environment is homeostasis A tool used to classify organisms using pairs of questions Dichotomous Key MORE VIRUS MORE BACTERIA MORE PROTIST MORE CLASSIFICATION Science Rocks! 200 100 200 100 200 100 200 100 200 100 400 200 400 20 400 200 400 200 400 200 600 300 600 300 600 300 600 300 600 300 800 400 800 400 800 400 800 400 800 400 1000 500 1000 500 1000 500 1000 500 1000 500 Why doesn’t the doctor prescribe an antibiotic for a viral infection? An antibiotic cannot destroy the outer protein coat of a virus. How is a virus like a parasite? They both need a host cell. How does a virus move? air, food, water, or contact with a contaminated person or object Why are viruses considered non-living particles? They do not show all the characteristics of living things. Name a common virus. chicken pox, common cold, influenza (flu) A bacteria is classified as a(n)_________ because it _________ have a nucleus. A bacteria is classified as a prokaryote because it does not have a nucleus. Name a common bacterial infection. strep throat or staph infection What process results in bacteria that are genetically different? conjugation Name two shapes of bacteria. spherical, rod-like, or spiral What determines the shape of a bacterial cell? the make up of the cell wall What structure allows an amoeba to move? pseudopods What structure allows a paramecium to move? cilia What structure allows a euglena to move? flagellum An amoeba is considered a(n) __________ protist. a. animal-like b. plant-like c. fungus-like a. animal-like A euglena is considered a(n) _________ protist. a. animal-like b. plant-like c. fungus-like b. plant-like Who developed the classification system called binomial nomenclature? Linnaeus Explain the correct way to write your scientific name. The first letter of the first word must be capitalized, and the entire name should be italicized. If you handwrite the scientific name, it must be underlined. What is the study of how living things are classified? taxonomy What is the scientific name for humans? Homo sapiens Which domain(s) include(s) only prokaryotes? Archaea and Bacteria This type of observation does not involve numbers Qualitative When you use your senses to gather information about the environment you are observing. When you look at a picture of a cell in a book ( because it is a representation ), you are using a Model Making an inference about a future event. predicting Interpreting an observation is making an inference
