Question

Viruses did not find a place in classification since

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
	**Primary Concept**:  Classification of organisms and the criteria for life.
	**Related Topics**: Characteristics of living things, biological classification, viral structure.
	**Prerequisites**: Basic understanding of what defines a living organism and the nature of viruses.
## SOLUTION PATHWAY
**Given Information**:
	The question asks why viruses are not classified in the standard biological classification.
**Method & Steps**:
	1. Recall the characteristics of living organisms: cellular structure, metabolism, reproduction, growth, response to stimuli, and homeostasis.
		Reasoning: Viruses lack most of these characteristics; they rely on a host for replication and metabolism.
	2. Analyze each option in light of the above:
		Option A: Correct. Viruses are not considered truly living because they lack cellular structure and cannot replicate independently.
		Option B: While true (they are non-cellular), this is not the primary reason they are not classified as living organisms.
		Option C: Being an obligate parasite is a characteristic of some viruses but not the main reason for non-classification.
		Option D: Pathogenicity is a consequence of viral infection, not a defining feature for their lack of classification.
	3. Final Answer:
		Result: A
		Verification: The core reason for the exclusion of viruses from classification is that they are not considered truly living entities.
 ## OPTION ANALYSIS
[A] ✓: This is the correct option as it correctly identifies the primary reason for the lack of classification of viruses.
[B] :x: While true, this is not the core reason for their exclusion from classification.
[C] :x: Being obligate parasites is a characteristic but not the fundamental reason.
[D] :x: Pathogenicity is a consequence of their biology, not the basis for their non-classification.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. [Error 1]: Confusing characteristics of viruses with the core reasons for classification; viruses are non-cellular and obligate parasites, but not all non-cellular and parasitic entities are excluded from classification.
		2. [Error 2]: Focusing on secondary aspects of viruses (pathogenicity) rather than their basic life-status.
	**Quick Tips**:
		1. Focus on the core characteristics of life when classifying organisms.
		2. Remember that viruses are acellular and require a host for metabolism and reproduction.
