Multiple Choice

Why is a culture diluted during plate counts?

Because it would be incredibly tedious to count all of the viable cells in an undiluted sample.

To give the microbiologist an easy number of viable cells to count.

To remove the dead or non-viable cells from the microbial culture.

Verified step by step guidance

Understand the purpose of dilution in microbiology: Dilution is used to reduce the concentration of cells in a sample to a manageable level for counting.

Consider the practical aspect: Counting all viable cells in an undiluted sample can be tedious and impractical due to high cell density.

Recognize the goal of dilution: It aims to provide a countable number of viable cells, making it easier for microbiologists to perform accurate plate counts.

Evaluate the options given: Option A states the tedious nature of counting undiluted samples, and Option B highlights the ease of counting viable cells after dilution.

Determine the correct answer based on the explanations: The correct answer should include the options that align with the purpose and practical benefits of dilution in plate counts.
