Question

Analyse the following statements and identify the correct options given below
I. Two kingdom system of classification did not distinguish between the eukaryotes and prokaryotes, unicellular and multicellular organism and green algae and fungi.
II. The two kingdom classification used for a long time was found inadequate

B VENKAT · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A. Both statements I and II are correct
## CONCEPT FRAMEWORK
	**Primary Concept**: Two-Kingdom Classification System
	**Related Topics**: Five-Kingdom Classification, Biological Classification, Taxonomy
	**Prerequisites**: Basic understanding of biological classification and its limitations.
## SOLUTION PATHWAY
**Given Information**:
	Two statements regarding the limitations of the two-kingdom classification system.
**Method & Steps**:
	1. **Analyze Statement I**: The two-kingdom system (Plants and Animals) indeed failed to differentiate between several key biological groups like prokaryotes and eukaryotes, unicellular and multicellular organisms, and placed organisms like green algae and fungi together in the plant kingdom despite their significant differences.
		Reasoning: The two-kingdom system was based primarily on gross morphology and lacked the tools to differentiate based on cellular structure and other key characteristics.
	2. **Analyze Statement II**: As biological knowledge expanded, the limitations of the two-kingdom system became increasingly apparent.  It couldn't accommodate the growing diversity of life discovered, leading to its inadequacy.
		Reasoning: The discovery of microorganisms and a better understanding of cellular structures highlighted the need for a more comprehensive classification system.
	3. **Combine Analyses**: Both statements accurately describe the limitations of the two-kingdom classification system.
		Result: Both statements I and II are correct.
## OPTION ANALYSIS
[A] ✓: Both statements accurately describe the limitations of the two-kingdom classification, which failed to differentiate between several key biological groups and was ultimately found inadequate as biological knowledge expanded.
[B] :x: Both statements are individually correct and accurately reflect the limitations of the two-kingdom classification.
[C] :x: Statement II is also correct, as the inadequacy of the two-kingdom system led to the adoption of more comprehensive systems like the five-kingdom classification.
[D] :x: Statement I is correct, as it highlights the fundamental inability of the two-kingdom system to differentiate based on key biological characteristics.
## LEARNING AIDS
	**Common Mistakes**:
		1. Overlooking the historical context: It's important to remember that the two-kingdom system was developed when our understanding of biology was limited.  Judging it solely by modern standards is unfair.
		2. Confusing with other classification systems: Be sure to focus on the specific limitations of the two-kingdom system, not those of other systems.
	**Quick Tips**:
		1. Remember the key groups that the two-kingdom system failed to differentiate: prokaryotes/eukaryotes, unicellular/multicellular, and green algae/fungi.
		2.  The inadequacy of the two-kingdom system was a major driver for the development of more complex classification systems.
