Question

The formation of biofilms by bacteria is facilitated by the sticky nature of their:

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Biofilm formation and bacterial adhesion
 **Related Topics**: Glycocalyx, extracellular polymeric substance (EPS), microbial communities
 **Prerequisites**: Basic understanding of biofilms and bacterial cell structures.
## SOLUTION PATHWAY
**Given Information**:
The question asks about the component responsible for the stickiness facilitating biofilm formation.
**Method & Steps**:
1. Consider the role of each component in biofilm formation:
  Reasoning: Biofilms are formed by bacterial cells adhering to a surface and each other. The sticky component is crucial.
  Formula/Rule: None directly applicable.
2. Analyze the options:
  Working:
		* A. Cell membrane: Regulates transport, not directly involved in adhesion.
		* B. Nucleoid: Contains bacterial DNA, unrelated to adhesion.
		* C. Glycocalyx: The sticky outer layer, essential for biofilm formation.
		* D. Mesosomes: Internal membrane invaginations, not involved in adhesion.
  Key Point: The glycocalyx's sticky nature is essential for biofilm formation.
3. Choose the correct answer:
  Result: C. Glycocalyx
  Verification: The glycocalyx forms the extracellular matrix of biofilms, providing the necessary stickiness.
 ## OPTION ANALYSIS
A :x: The cell membrane is not directly involved in the stickiness of biofilms.
B :x: The nucleoid is the bacterial chromosome, not involved in adhesion.
C ✓: The glycocalyx is the sticky extracellular layer responsible for biofilm formation.
D :x: Mesosomes are internal membrane structures not related to biofilm formation.
 ## LEARNING AIDS
 **Common Mistakes**: Confusing the role of other bacterial structures with the glycocalyx.
  How to avoid: Focus on the sticky nature required for biofilm formation.
 **Quick Tips**: Remember that the glycocalyx forms the extracellular matrix of biofilms.
