EA 1-3 Flashcards
Archaean are organisms who can live on very extreme conditions such as hot springs, very salty environment, or places who lacks oxygen
t/f
true
Utilizes light from the sun to manufacture their own food
photoautotroph
Organism who can manufacture their own food
autotroph
Utilizes inorganic compounds like iron to manufacture their own food
chemoautotroph
Utilizes organic compounds as their energy source
organotroph
Utilizes minerals from rocks for their energy source
lithotroph
Organism who feeds for their energy source
heterotroph
Endosymbiotic hypothesis suggests prokaryotes are cells who engulf eukaryotes, hence the latter becomes part of their cellular system
t/f
false
Various colonies with different shapes and characteristic in petri dish is considered as a population
t/f
false
Colonies of pure culture in petri dish is considered a population
t/f
true
An eocyte is a prokaryote believed to be the ancestor of both archean and eukaryotes.
t/f
true
Live on very salty environments
halophiles
Live on very cold environments
psychrophiles
Live on very hot environments
hyperthermophiles
Anaerobic Archaean that produce methane as by product
methanogens
Protozoans can move using flagella, pseudopodia, or cilia
t/f
true
Yeasts are protists
t/f
false
Nitrogen fixers are bacteria that can convert nitrogen gas that can convert useful nitrogen derivatives like nitrites and nitrates
t/f
true
Eurkaryogenesis is a process to which eukaryotes are derived from archaean ancestor
t/f
true
Conidia spores are used by paramecium if the environmental condition is unfavorable for their survival.
t/f
false
Whip like appendage in some bacteria used for locomotion
flagella
Used by magnetotactic bacteria for their movement in reference to the Earth’s magnetic field
magnetostomes
Movement due to sliding adherence of microbes on surfaces
gliding movement
Utilized by microbes to float (buoyancy) on water environment
gas vesicles
