Question

multiple choice question

the critical number of cells required to release inducer molecules in order to form a biofilm is a ______.

• quorum
• batch
• concentration
• colony

Explanation:

Analyze the definition of cell density threshold in biofilm formation

The question asks for the term describing the "critical number of cells required to release inducer molecules in order to form a biofilm."

Evaluate the given options

• quorum: Refers to the minimum number of members (or cells) necessary to conduct business or trigger a collective physiological response (such as biofilm formation via quorum sensing).
• batch: Refers to a closed-system microbial culture.
• concentration: Refers to the abundance of a constituent divided by the total volume of a mixture.
• colony: Refers to a visible mass of microorganisms originating from a single mother cell.

Select the correct term

The term that specifically represents this critical threshold number of cells is a "quorum."

Answer:

• quorum (Correct answer)
• batch
• concentration
• colony
