Definition
Specialized area of biology that deals with organisms ordinarily too small to be seen without magnification.
Microbiology
Resolving power, the ability of a microscope lens to distinguish between two separate entities that sit near one another, ability to show detail.
Resolution
Bacteria that grow at a basic pH are _________________.
Alkaliphiles
TRUE OR FALSE: Viruses are single-cellular particles
FALSE - Viruses are non cellular particles
Organisms whose optimal growth conditions are in basic PH
alkaliphile
Time it takes for a population to double in number
Generation time
Range of resolution of an Electron Microscopy
Nanometer
The way bacteria reproduce. Splitting of a parent cell into two equal parts.
Binary Fission
COMMON FEATURE OF ALL VIRUSES:
Cannot synthesize their own ________. (Needs host ________ synthesis machinery.)
Protein
YES OR NO: Can organisms be extremophilic to >1 condition?
YES
Examples:
Ocean Floor - Psychrobarophiles
Soda Lakes - Haloalkaliphiles
Physical or chemical agent used to inhibit or destroy microorganisms on skin or tissue
Reduce but do NOT eliminate bacterial growth
Antisepsis
Using a Dark Field Light Microscopy what types of cells can be examined?
Thin bacteria
Flagella
In the phases of typical bacterial growth curve: Name the two phases which the cell #s are changing
Log (increasing)
Death (decreasing)
NAME THAT VIRUS FORM: Animal/Plant or prophase (bacteriophage) virus integrates its genome in the host genome
Provirus
Needs small amounts of air to survive
Microaerophiles
Growth medium where some components are not defined
Synthetic (Defined) Medium
What are the four types of Light Miscroscopy
Bright Field
Dark Field
Phase Contrast
Fluorescence
There are 4 phases of typical bacterial growth. During the ________ (3rd) phase stress response turns on and number does not change.
Stationary
Viruses usually are specific to their host and in case of animal viruses, specific to host's ___________.
Extremophilic or not, organisms are adapted to their optimum growth conditions because their ____1____ are intact and their ____2____ are most functional.
1.) Cell Membrane
2.) Proteins
Sudden introduction of a previously limiting nutrient
Eutrophication
What is the property of light for Bright Field - Light Microscopy:
EX: Scattering, Refraction Bending, Absorption, Fluorescence
Absorption
Endospores - genetic material surrounded by protective spore coat
when conditions are favorable.. Spores germinate
Biofilms - resistant structures start by cells sticking to a surface
YES OR NO: During the Lysogenic Replication Cycle, the virus integrates in the host genome. Do new virus particles assemble at this time?
No.
No new virus particles are assembled.
__% of functions in a cell are carried out by proteins (not 100% of function)
90%
