Question

Which of the following components provides sticky character to the bacterial cell?

NISHANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
**Primary Concept**: Bacterial Cell Structure and Function
**Related Topics**: Glycocalyx, Cell Wall, Nuclear Membrane, Plasma Membrane
**Prerequisites**: Basic knowledge of bacterial cell components.
## SOLUTION PATHWAY
**Given Information**:
- Question asks for the component responsible for stickiness in bacterial cells.
**Method & Steps**:
1. Recall the function of each listed component.
Reasoning:  The question requires recalling specific functions of cellular structures.
2. Identify the component known for its sticky nature.
Working: Glycocalyx is known for its sticky, outer layer that aids in attachment.
3. Select the correct option.
Result: The glycocalyx is the correct answer.
Verification: Glycocalyx is directly associated with bacterial adhesion.
## OPTION ANALYSIS
[A] ✓: The glycocalyx is a sticky layer of polysaccharides or polypeptides that surrounds the bacterial cell and aids in attachment and biofilm formation, providing the sticky character.
[B] :x: The cell wall provides structural support and rigidity, not stickiness.
[C] :x: Nuclear membrane is not present in bacteria. This is a eukaryotic structure.
[D] :x: The plasma membrane controls the passage of substances into and out of the cell, but does not primarily contribute to stickiness.
## LEARNING AIDS
**Common Mistakes**:
1. Confusing cell wall with glycocalyx: The cell wall provides rigidity, while the glycocalyx provides stickiness.
2. Not remembering the specific function of the glycocalyx: Remember that the glycocalyx aids in attachment.
**Quick Tips**:
1. Remember that 'glyco' refers to sugars which are often sticky.
2.  Focus on the function of adhesion when thinking about the glycocalyx.
