Differentiate between cell mass and cell number
sergiy2304 [10]

Answer:

Measurement (Count) of Cell Numbers:

1. Breed Method:

A known volume of microbial cell suspension (0.01 ml) is spread uniformly over a glass slide covering a specific area (1 sq. cm). The smear is then fixed by heating, stained, examined under oil immersion lens, and the cells are counted.

Customarily, cells in a few microscopic fields are counted because it is not possible to scan the entire area of smear. The counting of total number of cells is determined by calculating the total number of microscopic fields per one square cm. area of the smear.
