ocular lens(es) 
the eyepiece(s)
objective lenses 
the lenses on a rotating turret that include:
Scanning (red-banded)
Low (yellow-banded)
High dry (blue-banded)
Oil immersion (white-banded or black) not used in this course
stage control knobs 
knobs found on the right side of the scope and toward the back of the stage, including:
The top knob to move the stage forward and backward
The bottom knob to move the stage left and right
microscope stage
where the slide sits
stage clips 
part of the microscope stage that holds a slide in place
coarse focusing knob 
> the "outside knob"
> known as the big knob
> located on both the right and left sides of the scope
> used initially to get the slide in focus
fine focusing knob
> nested within the coarse focusing knob
> fine tunes the object and brings it into focus clearly
condenser adjustment knob 
> located on the left side
> moves the condenser directly under the stage seen through the center hole in the stage up and down
> straightens the beam of light as it shines up the scope
iris diaphragms
increases or decreases the amount of light shining through located on the:
Condenser
Light source
light 
bulb that illuminates the slide through a hole in the stage
base 
the bottom portion of a microscope
arm 
supports the lens mechanism
How is total magnification calculated? 
ocular x objective
What magnification is the eyepiece (ocular) typically at?
ten power (10X)
What magnification are the three objective lenses at?
4X, 10X, and 40X (scanning, low, and high, respectively)
How is the light adjusted on a microscope?
Through the iris diaphragm located on the:
Condenser
Dimmer (rheostat knob)
How is a slide made?
(1) Take a slide.
(2) Place specimen on slide.
(3) Add a cover slip.
(4) Add a stain if needed.
What is never used while on high power?
The coarse focusing knob is never used on high power, as it could crack the slide.
ecosystem 
an area where all of the organisms interact with their physical environment to produce a flow of energy
abiotic 
non-living
biotic 
living
producers 
> organisms that can produce their own food within their bodies
> ex. green plants, algae, and other forms of life which undergo photosynthesis
> autotrophs
autotrophs
> self-feeding organisms
> producers
consumers
> organisms that do not make their own food and depend on other organisms for consumption
> ex. zebras, lions, and bald eagles
> heterotrophs
heterotrophs 
> other-feeding (living or dead) organisms
> consumers
primary consumers 
> organisms that eat the producers directly
> heterotrophs
> ex. plant eaters (herbivores), zebras, and tadpoles
secondary consumers 
> organisms that eat primary consumers
> heterotrophs
> ex. lions, hawks, and rattlesnakes
tertiary consumers 
> organisms that eat secondary or primary consumers
> heterotrophs
> ex. owls and bald eagles
quartenary consumers 
> organisms that eat the tertiary, secondary, or primary consumers (all are carnivores)
> heterotrophs
> ex. lions, wolves, polar bears, and hawks
decomposers 
> bacteria and fungi that break down dead creatures into their constituent elements and are crucial for the recycling of substances within an ecosystem
> heterotrophs
detritivores 
> creatures that eat partially decomposed material (detrius)
> heterotrophs
> ex. earthworms and some insects
plankton 
microscopic organisms that are suspended in water with little or no ability to swim
types of plankton
(1) Phytoplankton
(2) Zooplankton
phytoplankton
> "plant-like" plankton
> autotrophs
> ex. green algae, diatoms, and dinoflagellates
zooplankton 
> "animal-like" plankton
> heterotrophs
> ex. hydra, jellyfish, and krill
amoeba proteus 
> heterotroph
> phagocytosis
paramecium 
> heterotroph
> food collected by their cilia enters their oral groove
vorticella 
> heterotroph
> feed on bacteria or other protozoans
elodea 
> autotroph
> photosynthesis
cheeks 
> heterotroph
> mitochondria produce chemical energy
