Question

Glycocalyx (mucilage sheath) of a bacterial cell may occur in the form of a loose sheath called …A… or it may be thick and tough called …B…   Choose the correct pair from the given option

NISHANTH · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
	**Primary Concept**: Bacterial Cell Structure and Function
	**Related Topics**: Glycocalyx, Capsule, Slime Layer, Cell Wall, Plasma Membrane
	**Prerequisites**: Basic understanding of prokaryotic cell structure.
## SOLUTION PATHWAY
**Given Information**:
	The question asks about the two forms of glycocalyx in bacterial cells.
**Method & Steps**:
	1. **Understanding Glycocalyx**: Glycocalyx is a layer of polysaccharides and/or proteins secreted by bacterial cells external to the cell wall. It can have two forms.
		Reasoning: The glycocalyx has protective functions and can vary in thickness and organization.
	2. **Differentiating Slime Layer and Capsule**: A loose, unorganized, and easily removable glycocalyx is called a slime layer. A thick, well-organized, and tightly bound glycocalyx is called a capsule.
		Working:  The question describes 'A' as a loose sheath and 'B' as a thick and tough layer.
		Key Point: The capsule provides greater protection against desiccation and phagocytosis compared to the slime layer.
	3. **Matching with Options**: The description of 'A' matches with 'slime layer' and 'B' matches with 'capsule'.
		Result: The correct pair is 'Slime layer, Capsule'.
		Verification: This aligns with the definitions of slime layer and capsule.
## OPTION ANALYSIS
[A] ✓: 'Slime layer, Capsule' is the correct answer as explained above. 
[B] :x: 'Capsule, Slime layer' is incorrect. The order is reversed.
[C] :x: 'Cell wall, Plasma membrane' is incorrect. These are entirely different structures within the bacterial cell, not related to glycocalyx.
[D] :x: 'Tonoplast, Leucoplast' is incorrect. These are plant cell structures, not found in bacteria.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing the order of slime layer and capsule: Remember that 'slime' implies loose and 'capsule' implies a well-defined structure.
		2. Confusing bacterial structures with those of other organisms: Pay attention to the specific context of the question (bacterial cell).
	**Quick Tips**:
		1. Visualize the slime layer as a loose cloak and the capsule as a tight armor.
		2. Remember 'S' for Slime (loose) and 'C' for Capsule (compact).
