List and describe the groups of algae:
Give this one a try later!
1. Pigmented Flagellates:
-Colored with pigments. Determines which type of light will be absorbed.
2. Nonmotile forms:
-Cannot move on their own; move with their environment
3. Diatoms
- Cell wall is made of silica, which doesn't decompose.
- Sinks to the bottom of the ocean and becomes diatomaceous earth,
which is used in filtering systems.
Loop Dilution
Give this one a try later!
, Utilizing a loop to generate less concentrated microbial solutions, with the
goal of producing an isolated colony
Stock culture
Give this one a try later!
A collection of a pure culture maintained for future study in a laboratory
setting.
Septate
Give this one a try later!
Intercellular walls in the hyphae of fungi
Magnification
Give this one a try later!
The ability of a lens to enlarge the visual appearance of an object.
1. Scanning or low power - 4x
2. Medium Power - 10x
3. High, Dry - 40x
4. Oil Immersion - 100x
**Ocular lens = additional 10x**
,Bacterial Growth
Give this one a try later!
Division of bacterial cells by binary fission. This does not refer to an
increase in size.
Mycelium
Give this one a try later!
Group of multi-branched hypha, which can eventually become visible to
the naked eye.
Describe, in detail, the steps of aseptic technique for inoculating broth and agar
media.
Explain why the openings of the tubes are heated.

1. Flame the loop and flame the lip constantly.
2. To create an updraft.
Identify and properly use an inoculating loop.

, Flame it before and after (almost) every interaction.
Deep tube
Give this one a try later!
An agar media prepared in a tube that was kept upright as the solution
reach its solidification temperature.
Saprophytes
Give this one a try later!
Consumer bacteria. Derives its nourishment from dead or decaying
bacteria.
Myoneme
Give this one a try later!
Contractile structure found in some single celled eukaryotes, particularly
vorticella. Consists of a series of protein filaments which contract rapidly
upon exposure to calcium.
Differential media
