4.3.2: Fill-In-The-Blank

1. A group of genetically identical cells attached to one another that give rise to a single colony on the surface of solid media is referred to as a .

2. The device used to hold the sample for a direct microscopic count is called a .

3. When using the viable plate count method to count bacteria in a sample, it is important to perform a serial of the original sample so there is a statistically valid number of colonies to count.

4. A is a growth of bacteria on the surface of solid media that contain genetically identical cells.

5. When performing a standard plate count (viable plate count), plates that contain to colonies are selected for counting.

6. Viable plate counts are also known as .

7. The dilution factor is the of the dilution.

8. Cells originally deposited on the agar undergo many rounds of to produce the observable growth of a colony.

9. In a direct microscopic count, the sample moves from the edge of the cover slip into the chamber by .

10. The direct microscopic count does not differentiate cells from cells.

11. Bacterial cells in the counting chamber are visualized and counted using the objective lens.
