Chapter 1 Flashcards
(45 cards)
Ubiquitous
Found everywhere
Linneaus
Scientist that invented Binomial nomenclature
Scientific name
Genus + specific epificit
Eukaryotic vs Prokaryotic
Eukaryotic organisms have membrane-bound organelles (Golgi apparatus, Mitochondria, etc)
Prokaryotes lack a nucleus and don’t have membrane bound organelles
5 Kingdoms From least complex to most complex
Least: Monera, Protista, Fungi, Plantae
Most: Animalia
Monera
Cellular type (unicellular/multicellular)
Prokaryotic VS eukaryotic
Domain name
Group names for organisms
Least complex animal kingdom
Unicellular
Prokaryotic
Domain: bacteria & Archae
What does domain classification depend on
number and type of ribosomes
What is binomial nomenclature
A way to classify organisms by two names
Genus + specific epithet
Protista:
Cellular type (unicellular/multicellular)
Prokaryotic VS eukaryotic
Domain name
Group names for organisms
Primarily unicellular some are multicellular
Domain name = Eukarya
Group names = Slime mold, Protozoa, Algae
Plantae
Cellular type (unicellular/multicellular)
Prokaryotic VS eukaryotic
Domain name
Group names for organisms
Multicellular
Eukaryotic
Domain = Eukarya
Animalia
Multicellular
Eukaryotic
Domain = Eukarya
Classification = # + type ribosomes
Fungi
Cellular type (unicellular/multicellular)
Prokaryotic VS eukaryotic
Domain name
Group names for organisms
Mostly Multicellular few unicellular (yeasts)
Eukaryotic
Domain name = Eukarya
Group names = Yeasts, molds, mushrooms
Are viruses classified into a domain
No, because they don’t have ribosomes and be classified into a domain, requires the number and type of ribosome
Are viruses classified into a domain
No, because they don’t have ribosomes and be classified into a domain, requires the number and type of ribosome
List the general characteristics of viruses
All viruses have protein coats called capsids that contain genetic information
What are helminths? Why do we care?
Parasitic worms (flatworms, tapeworms…)
part of life cycle is microscopic
Who discovered life’s smallest unit (cells)? And what theory did he come up with?
Robert Hooke
Cell Theory-all living things comprised of cells
What was Redi known for
Spontaneous generation
Maggots came from flies that lay eggs not spontaneous generation in decaying meat
Who was the first to see microbes through a magnifier?
Van Leeuwenhoek
called them animalcules
Disprove spontaneous generation
What was Virchow known for
Biogenesis concept; living cells arise only from preexisting living cells
Disprove spontaneous generation
What did Pasteur discover about microrganisms?
Air contains microrganisms that can contaminate sterile solutions
Microrganisms can be found on nonliving matter,
Microrganisms destroyed by heat
Pasteurization = heating liquids can kill microbes but doesn’t sterilize the liquid
Aseptic technique = methods to decrease contamination
Who is Lister and what did he do
Germ theory of disease-microrganisms might cause disease
Used phenol post surgery to reduce infection
What was Robert Koch known for
Diseases caused by specific microoganism
Koch’s Postulates = relates specific microniganism to specific disease
What was Jenner credited/ know for?
Used cowpox like antigen to protect against smallpox
Credited with inventing Immunity
