Question

Which of the following structures contributes to the adhesive properties of a bacterial cell?

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Bacterial cell structure and function
 **Related Topics**: Glycocalyx, adhesion, biofilm formation, bacterial virulence
 **Prerequisites**: Basic understanding of bacterial cell components.
## SOLUTION PATHWAY
**Given Information**:
The question asks about the structure responsible for bacterial adhesion.
**Method & Steps**:
1. Consider the functions of each option:
  Reasoning: We need to identify the structure that directly facilitates attachment to surfaces.
  Formula/Rule: None directly applicable.
2. Analyze the roles of each structure:
  Working:  
		* A. Cell wall: Provides structural support and shape, not primarily adhesion.
		* B. Plasma membrane: Regulates transport, not directly involved in adhesion.
		* C. Glycocalyx: A sticky outer layer composed of polysaccharides and/or polypeptides, directly responsible for adhesion to surfaces and biofilm formation.
		* D. Ribosomes: Involved in protein synthesis, unrelated to adhesion.
  Key Point: The glycocalyx's sticky nature is key to its adhesive properties.
3. Identify the correct answer:
  Result: C. Glycocalyx
  Verification: The glycocalyx is known to mediate bacterial adhesion and biofilm formation.
 ## OPTION ANALYSIS
A :x: The cell wall provides structural support, not adhesion.
B :x: The plasma membrane is involved in transport and cellular function, not primarily adhesion.
C ✓: The glycocalyx is a sticky outer layer that facilitates bacterial adhesion.
D :x: Ribosomes are involved in protein synthesis, unrelated to adhesion.
 ## LEARNING AIDS
 **Common Mistakes**: Choosing cell wall or plasma membrane due to their importance in overall bacterial structure.
  How to avoid: Focus on the specific function of adhesion.
 **Quick Tips**: Remember the glycocalyx as the 'sticky' outer layer of bacteria.
