match the method of counting bacteria with the statement that describes it. 1 direct cell count 2 flow cytometry 3 turbidometry 4 coulter counter match each of the options above to the items below. a spectrophotometer is used to measure the light scattering properties of a bac bacteria increase, more light is scattered and less is transmitted to the detector. this method uses a special slide (cytometer) and cells are counted by observing this is an automated cell counting device that scans a culture as it passes throu this is an automated cell counting device that requires fluorescent labeling of c

Explanation:

1. Turbidometry uses a spectrophotometer to measure light - scattering properties of bacteria. As the number of bacteria increases, more light is scattered and less is transmitted.
2. Direct cell count uses a special slide (cytometer) and cells are counted by observation.
3. Coulter counter is an automated cell - counting device that scans a culture as it passes through.
4. Flow cytometry is an automated cell - counting device that requires fluorescent labeling of cells.

Answer:

A spectrophotometer is used to measure the light scattering properties of a bacteria. As bacteria increase, more light is scattered and less is transmitted to the detector. - 3. Turbidometry
This method uses a special slide (cytometer) and cells are counted by observing - 1. Direct cell count
This is an automated cell counting device that scans a culture as it passes through - 4. Coulter counter
This is an automated cell counting device that requires fluorescent labeling of cells - 2. Flow cytometry
