Question 1: List the three domians

Answer:

Bacteria, Archaea, Eukarya (Protists, Fungi, Plants, Animals)

Question 2: Identify the importance of Koch's postulates.

Answer:

It related a specific microbes to a specific disease.

Question 3: Define mycology

Answer:

the study of fungi

Question 4: Explain how Pasteur's work influenced Lister and Koch.

Answer:

Lister heard about Pasteur's working connecting microbes to animal disease and applied it to disinfectanting microbes by washing hand before surgery would decrease infections. Koch determined microbes cause disease, placing harmful bacteria in healthy ani

Question 5: Describe Fungi

Answer:

Eukaryotes, Chitin cell walls, chemoautotroph. Molds & mushrooms are multicellular, consist of mycelia, which composes of filaments called hyphae. Yeast ony unicellular fungi. heterotrophs. reproduce asexually by spore & sexually by gametes

Question 6: Define parasitology

Answer:

the study of protozoa and parasitic worms

Question 7: Identify the importance of Jenner's work.

Answer:

He was able to provide vaccination from smallpox disease resulting in immunity from that disease Question 8: Explain the importance of observations made by Hooke and van Leeuwenhoek.

Answer:

Hooke reported to the world that life's smallest structure units were "lttle boxes" or "cells", which marked the beginning of cell theory- that all living things are composed of cells. Leeuwenhoek was the first to see cells with better scope "animalcules"

Question 9: define immunology

Answer:

the study of immunity

Question 10: Describe Algae

Answer:

Eukaryotes, cellulose cell walls, Use photosynthesis for energy, produce molecular oxygen and organic compounds Question 11: Recognize the system of scientific nomenclature that uses two names: a genus and a specific epithet.

Answer:

Linnaeus established the system of scientific nomenclature.Are italicized, genus is capitalized, specific is lowercase.Maybe descriptive or honor a scientist ex.

• Coli- honor discoverer, Theodor Escherich, describes the bacterium's habitat

Question 12: Describe Viruses

Answer:

Acellular or Subcellular, Consist of DNA or RNA core, core surrounded by protein coat, coat maybe encloses in a lipid envelope. Only replicated when they are in living host cell-obligate parasites. all types of cells can be infected by virus

Question 13: Define bacteriology

Answer:

the study of bacteria Question 14: Identify the contributions to microbiology made by Needham, Spallanzani and Pasteur.

Answer:

Prove that microorganisms exist in the air

Question 15: Describe Archaea

Answer:

Prokaryotic, Unicellular, reproduce binary fission, lack peptidoglycan in cell wall, for energy (organic, inorganic, photosynthetic), Live extreme enviroments- methanogen (feed on methane), extreme halophilies (salt-loving), thermophilies-heat loving

Question 16: List at least four beneficial activities of microorganisms.

Answer:

Converts chemical elements into forms that plants and animals can use. Microbes are used to recycle water. Used to clean pollutants. provide pest control for farmers.

Question 17: List several ways in which microbes affect our lives

Answer:

Some are pathogenic, Decompose organic waste, producers in the ecosystem by photosynthesis, produce chemicals such as ethanol and acetone, produce foods like vinegar,cheese, and bread.Prevent food spoilage, disease occurrence, and contamination in labs

Question 18: Describe Protozoa

Answer:

Eukaryotes, No cell wall, Unicellular, For energy absorb organic chem. mobile through pseudopods (false feet), flagella, cilia. Reproduce sexually and asexually. Maybe pathogenic

Question 19: Identify the contributions to microbiology made by Ehrlich and Fleming.

Answer:

Ehrlich found a chemotherapeutic agent called salvarsan that cure syphilis (first synthetic drug). Fleming discovered antibiotics when looking at mold that could inhibit growth of bacteria

Question 20: Compare spontaneous generation and biogenesis.

Answer:

Spontaneous generation is when scientists believed that some forms of life could arise spontaneously from nonliving matter. Biogenesis is the claim that living cells can arise only from preexisting living cells

Question 21: Explain the importance of molecular genetics and molecular biology

Answer:

microbial genetics studies the mechanisms by which microorganisms inherit traits. molecular biology studies how genetic info is carried in molecules of DNA and how DNA directs the synthesis of proteins.

Question 22: Describe Bacteria

Answer:

Prokaryotes. peptidoglycan cell walls. reproduce by binary fission. For energy, use organic chem, inorganic, photosynthesis. Unicellular (simpled-celled), can be commensal or pathogenic

Question 23: Define virology

Answer:

the study of virus
