TAXONOMY, BACTERIA AND VIRUSES REVIEW


The science of grouping and naming organisms is called

TAXONOMY


A step by step way to identify an organism using a series of paired descriptions

Dichotomous key


The taxon for animals that are warm blooded, have body hair, and produce milk for their young.

Mammalia


What is the naming system called that gives each organism a two word scientific name?Turdusmigratorius“American Robin”

Binomial nomenclature


Which scientific name is written correctly?

FelisConcolor

Felisconcolor

Felisconcolor

FelisConcolor


The names of the taxons from the most general to the most specific.

Kingdom, phylum, class, order, family, genus, species.


What level of classification is smaller than an order but larger than a genus?

  • Family


What is this diagram called?

  • Cladogram


Name the derived characteristic for the amphibians?

  • Four limbs


Which organisms are the most closely related?

  • Primates, Rodents and Rabbits


Which organisms are the most closely related?

Mountain Lion and Domestic Dog


What are the names of the three domains?

  • Archaea

  • Bacteria

  • Eukarya


Which two domains contain only unicellular, prokaryotic organisms?

  • Archaea

  • Bacteria


Organisms that make their own food.

Autotrophs


Organisms that must consume food.

Heterotrophs


Which kingdom contains organisms that are multicellular, eukaryotic, and autotrophs?

Plantae


Which kingdom contains organisms that are prokaryotes, unicellular, and live in extreme environments?

Archaebacteria


Which kingdom contains organisms that are prokaryotes, unicellular, and like to decompose dead matter?

Eubacteria


Which kingdom contains organisms that are eukaryotes, unicellular or multicellular, mobile and heterotrophs?

Protista


Which kingdom contains organisms that are multicellular eukaryotes, mobile and heterotrophs? They do not have cell walls.

Animalia


Which kingdom contains organisms that are multicellular eukaryotes, have cell walls with chitin, and absorb their food? Examples are yeast, mold, and mildew.

Fungi


A nonliving parasite

  • Virus


The outer protein coat of a virus

  • Capsid


A virus that infects a bacteria

  • Bacteriophage


What do viruses need to reproduce?

  • A living cell as a host


What type of viral infection is shown in the diagram?

  • Lytic infection


Lysogenic cycle

  • A virus cycle where a virus injects its DNA into a cell, reproduces normally, but does not cause the cell to lyse.


Are viruses alive?? Explain.

  • NO

  • Viruses do not have all the characteristics of living things.

  • Not made of cells

  • Cannot live independently.

  • Must infect a living cell to reproduce.


How do viruses cause disease?

  • By disrupting the cell’s equilibrium.


Identify the three shapes of bacteria

Bacillus – rod shaped

Spirillum – spiral shaped

Coccus - round


What is the term for a disease causing organism?

Pathogen


How do bacteria reproduce?

  • Binary Fission – Asexual Reproduction


What is the name of the process where two bacteria exchange part of their DNA to increase diversity?

Conjugation


Name two ways bacteria are beneficial.

  • Decomposeers

  • Nitrogen fixation

  • Used to produce food.

  • Digest food in the digestive tract.

  • Synthesize drugs such as insulin.

  • Cleanup oil spills.


Name two diseases caused by bacteria

  • Tetanus

  • Strep throat

  • Tuberculosis

  • Bacterial Meningitis

  • Lyme disease


Name two viruses that cause disease.

  • Influenza

  • HIV virus causes AIDS


What body system is affected by AIDS? What type of cells are infected by the HIV virus?

Immune system

Helper T Cells


What can you do to treat or prevent a viral disease?

  • Vaccines can prevent a viral disease.

  • Antibiotics do not work on viral diseases.
