|
Term
|
Definition
| Unicellular, eukaryotic, heterotrophic microorganisms. Have a life cycle that includes a vegetative throphozoite, and a resting cyst stage. |
|

Term
|
Definition
| A diverse group of simple, photosynthetic eukaryotic organisms with uncertain relatedness |
|
|
Term
|
Definition
| common in freshwater and are usually unicellular or colonial. EX: Spirogyra and Volvox |

| What are some other algal groups? |
|
Definition
| Red algae, Brown algae, golden-brown algae, yellow-green algae, and diatoms. |
|
|
Term
| How are algal groups differentiated? |
|
Definition
| They are differentiated by their photosynthetic pigments, motility, cell wall material, and storage carbohydrate. |
|

Term
|
Definition
Nonmotile eukaryotes
Cell wall made of chitin
Absorptive heterotroph(secrete exoenzymes then absorb nutrients)
Saprophytes (decompose dead organic matter)
Parisites
Divided into unicellular yeasts, and filamentous molds. |

|
Term
| Limit of resolution or resolving power |
|
Definition
Actual measurement of how far apart 2 points must be for the microscope to view them as being separate.
About 0.2 micrometers |
|
|
Term
| Formula to calculate limit of resolution |
|
Definition
Wavelength of light used
(NA Condenser +NA Objective) |
|
|
Term
|
Definition
| Measure of the lens's ability to capture light coming from the specimen and use it to make the image |
|
|
Term
|
Definition
| Special condenser is used so only the light reflected off the specimen enters the objective |
|
|
Term
| Phase contrast microscopy |
|
Definition
| uses special optical components to exploit subtle differences in the refractive indices of water and cytoplasmic components to produce contrast |
|
|
Term
|
Definition
| Uses a fluorescent dye that emits fluorescence when illuminated with UV radiation |
