Microbe Growth Vocab Flashcards
Chemoautotrophs
take their energy from chemicals and their carbon from inorganic materials
Chemoheterotrophs
take there energy from chemicals and their carbon from organic materials
Photoautotrophs
take their energy from light and their carbon from inorganic materials
Photoheterotrophs
take their energy from light and their carbon from organic material
Saprobes
decomposer microbes
Parasites
pathogenic, nutrients from living tissues
Simple Diffusion
substances move on a gradient from high to low concentration
Facilitated diffusion
molecules bind to receptor and are carried to the other side of the membrane according to the gradient
Carrier mediated active diffusion
molecules are pumped in or out by a special receptor
Group Translocation
molecules are transformed into useful substances as it crosses across the membrane
Bulk Transport
Endocytosis- transport of large cells, particles, or liquids by engulfment
Obligate Aerobes
grows only in O2
Obligate Anerobes
are killed by O2
Facultative Anaerobes
can grow with or without O2
Aerotolerant Anaerobes
unaffected by O2
Microaerophile
grows with specific amount of O2
Mesophiles
microbes that grow best in moderate temperatures
Psychrophiles
microbes that grow best in cold temperatures
Thermophiles
Microbes that grow best in high temperatures
Osmophiles
microbes that prefer high solute concentration (i.e. hypertonic solutions)
Barophiles
require high atmospheric pressure
Symbiotic
Close nutritional relationship that is essential for survival of at least one organism
Synergism
Organisms cooperate and share nutrients
Antagonism
some organisms are inhibited by others
