Isotonic Solution
Optimum environment for cell to thrive
Facultative Parasite
An organism that prefers to feed on non living matter, but can also feed on living matter
Water is necessary for growth & multiplication of organisms
Moisture
Dissolves food in the environment of bacterial cell so food can be better absorped
Moisture
Facultative Anerobe
An organism that prefers to live in an Oxygenated environment, but can also exist in a NON Oxygenated environment
Thermophile
An organism that prefers HOT temperatures (45-70C)
7.35-7.45
An organism has to be inbetween this pH to thrive in the human system
Facultative Aerobe
An organism that prefers to live in the absence of oxygen, but can also live in the presence of o2
Bacterial Colony
A group of bacteria growing on a solid medium arising from a single microorganism.
Yellow
Has least affect on bacterial growth
Aerobe
Organism that grows in the presence of Oxygen
Light
UV, Violet, Blue, Green, Red, Yellow
Synnergism
An association of 2 different organisms where the organisms multiply more rapidly together than an individual alone
Hypotonic Solution
solution with a LOW concentration of solute
Hypertonic Solution
Solution with a HIGH concetration of solute
Mesophile
An organism that prefers moderate temperatures (20-45C)
Solution
Homogenous mixture of 2 or more substances
Plasmoptysis
The process by which a bacterial cell will swell & burst (HYPOTONIC SOLUTION)
Mutualism
An association of 2 different organisms living close together, both mutally benefiting from each other.
Semi Permeable Membrane
Membrane which allows the passage of certain substances through it while restricting the passage of other substances
Solvent
Component of solution that is present in GREATER amount `
Facultative Saprophyte
An organism that prefers to feed on living matter, but can also feed on non living matter.
Ultraviolet
Most destructive to Bactera, denatures protein
Osmosis
Passage of a solvent (h2o) through a semi permeable membrane from an area of LOW solute concentration to an area of HIGHER solute concentration. (Just fluid moving)
Synnecrosis
An association of 2 different organisms where both are unhappy
Nutrients
Very important because an organism needs nourishment to thrive.
Antagonism
An association of 2 different organisms where the presence of one INHIBITS the growth of the other
Optimum Temperature
Temperature at which an organism grows BEST
Commensalism
An association of 2 different organisms in which one gains some benfit, and the other is undisturbed
Mesophile
20-45C Moderate Temp
Oxygen
Aerobe, Anerobe, Facultative Aerobe, Facultative Anerobe, Microaerophilic Organism
Water will leave cell, cell will shrink & die/plasmolysis/Osmosis
What will happen in a solution with a high concentration of solute? What is this process caled? Why?
Binary Fission
A method of asexual reproduction in which the cell splits into 2 parts, each of which develops into a complete individual.
Autotrophic Bacteria
2- Self nourishing bacteria that is capable of growing in the absence of organic compounds.
Heterotrophic Bacteria
Organism that obtains nutrients by breaking down organic matter from the environment into simple chemical substances (It Seeks an Organic Source from the environment)
Osmotic Pressure
Hyper tonic solution will cause PLASMOlYSIS HYPO tonic solution will cause PLASMOPTYSIS
Solute
Component of solution that is present in LESSER amount
Saprophyte
An organism that obtains nourishment from non-living matter
Parasite
An organism that obtains nourishment from living matter
pH
0-7 Acid/ 7-14 Base.
Symbiosis
The living together in close association of two different species
Temperature
Maximum Termp, Minimum temp, optimum temp, mesophile, thermophile, psychrophile
Mesophile
Human body temperature is 37C
Plasmolysis
The process by which a bacterial cell shrinks and dies (HYPERTONIC SOLUTION)
Parasitism
An association of 2 different organisms where one benefits and the other one is harmed
Anerobe
Organism that grows in the ABsence of oxygen
Water will enter cell, cell will swell & burst/plasmoptysis/osmosis
What will happen in a solution with a LOW concentration of solute? What is this process called? Why?
Maximum Temperature
The temperature ABOVE which bacterial growth will NOT take place
Concentration
Number of molecules of solute used in solution in RELATION to number of molecules in solvent
Micro Aerophilic Organism
An organism that grows beest in an amount of oxygen LESS thatn that which is contained in air.
Bonds of - will insulate micro organisms from any changes in temperature
Moisture
Participates in hydrogen bond formation to make molecules of protein
Moisture
Antibiosis
An association of 2 different organisms where one is DETRIMENTAL to the other.
Participates in chemical rxn/fxn that go on within the cell
Moisture
Major Component of Cytoplasm (70-80%h2o)
Moisture
7.0-7.35
pH for disease producing organisms
Autotrophic Bacteria
"Self Feeder" 1-Organism that obtains nutrients by building organic compounds in their cytoplasm from simple inorganic subtances
Organic / Inorganic
with Carbon (proteins/carbs/lipids) No Carbon (Calcium, magnesium, mineral salts)
Minimum Temperature
The temperature BELOW which bacterial growth will NOT take place
