Field of View |
The circle of light that you see when you look through the ocular lenses of the microscope |
|
Coarse Adjustment Knob |
To bring the object into focus |
|
Rotate the microscope stage upward (turn the knob away from you) until it stops, then slowly turn it towards you until the object is in focus. |
How do you use the coarse adjustment knob? |
|
Fine adjustment focus |
Bring the objects into sharp focus using this |
|
Diopter-Adjustment Ring |
To compensate for differences in visual strength of your eyes make adjustments using this |
|
Condenser |
Where light is transmitted through |
|
Iris Diaphragm of the Condenser |
To alter the brightness of light transmitted |
|
Parfocal |
The image will remain nearly in focus when you switch from one power to another |
|
Parcentered |
The image will remain nearly centered in the field of view when you switch from one power to another. |
|
Center of Focus |
Region in which objects are in sharp focus |
|
Depth of Field |
The vertical zone where an object is perhaps not in sharp focus but is still visible |
|
Cytoplasmic Streaming |
The circular movement of the cytoplasm within the cell |
|
45, 18, 5 |
How many divisions per field does a 4x , 10x and 40x have? |
|
Autotrophs |
Obtain their carbon from CO2 |
|
Heterotrophs |
Obtain performed organic carbon-containing molecules from other organisms |
|
Phototrophs |
Obtain their energy from light |
|
Chemotrophs |
Obtain their energy from the oxidation of organic and inorganic compounds |
|
Mixotrophs |
Obtain energy from inorganic sources and carbon from organic sources |
|
Taxa |
Classification group name |
|
Domain, Kingdom, Phylum, class, order, family, genus, species |
8 different taxonomic groups |
|
Supergroup |
A taxonomic group that further distinguishes eukaryotic organisms |
|
eukarya, bacteria, and archaea |
The three domains |
|
Shared derived character |
All organisms within a clade share this |
|
Clades |
Groups delineated by the two branches and their common ancestor |
|
Taxonomy |
The science of finding, describing, and naming organisms |
|
Phylogenetic tree |
Created using information from the fossil record, comparative anatomy, physiology and morphology using DNA sequences. |
|
Cladograms |
Are phylogenetic trees made up of a series of two way branching points |
|
Amoeba |
Domain: Eukaryotes Kingdom-Amoeboza, Phylum: Tubulinea |
|
Amoeba |
Appear to be amorphous blob, moves using pseudopodia, similar to human white blood cells in terms of appearance, locomotion, and feeding habits. They contain a nucleus, contractile vacuole, and a food vacuole |
|
Euglena |
Domain-Eukaryote, Kingdom-Euglenozoa, Phylum-Euglenida |
|
Euglena |
Have chloroplast like plants and are able to move/ absorb nutrients from the environment like animals.Have a red eyespot and two flagella to move along. Can bend their body to squeeze through small spaces. |
|
Euplotes |
Domain-Eukarya, Kingdom-Alveolata, Phylum-Ciliophora |
|
Euplotes |
Oval shaped transparent body surrounded by a rigid pellicle. Uses cilia to guide food particles into its oral groove. It's large macronucleus looks like a backwards letter C. |
|
Paramecium |
Domain-Eukarya, Kingdom-Alveolata, Phylum-Ciliophora |
|
Paramecium |
One celled organism which has almost twice as many genes as humans do. Covered with cilia which allow it to swim ten times its body length in one second. |
|
Blepharisma |
Domain: Eukarya, Kingdom: Alveolata,Phylum: Ciliophora |
|
Blepharisma |
Have small memebrane-bound cavities just under their cell surface. Function is unknown. Feeds on small protists and bacteria and will often appear to be pink or red due to pink pigment held in vesicles. |
|
Stentor |
Domain-Eukarya, Kingdom-Alveolata, Phylum-Ciliophora |
|
Stentor |
Filter feeding, heterotrophic ciliate protists. Either Trumpet or bowling pin shaped. Among the largest unicellular organisms, and contains a contractile vacuole to combat osmosis. Have amazing regenerative process. Often clear but can exist in several colors. |
