Question

State whether the given statements are true or false I. Five kingdom system of classification did not differentiated between the heterotrophic group, fungi and the autotrophic green plants, through they showed a characteristic difference in their walls composition. II. Fungi wall contains chitin, while the green plants has a cellulosic cell wall Codes

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
	**Primary Concept**: Five Kingdom Classification and Cell Wall Composition
	**Related Topics**:  Heterotrophic and Autotrophic nutrition, Fungi, Plants, Cell wall components (chitin and cellulose)
	**Prerequisites**: Basic understanding of the five kingdom classification, plant and fungal cell wall structures.
## SOLUTION PATHWAY
**Given Information**:
	Statement I: Five kingdom system did not differentiate between fungi and green plants based on wall composition.
	Statement II: Fungal walls contain chitin and plant cell walls are made of cellulose.
**Method & Steps**:
	1. **Analyze Statement I**: The five kingdom system (proposed by Whittaker) *did* differentiate between fungi and plants, primarily based on their mode of nutrition (heterotrophic vs autotrophic) and cell wall composition. Fungi were placed in their own kingdom, separate from plants, due to their heterotrophic nature and chitinous cell walls. Statement I is therefore FALSE.
		Reasoning: The five kingdom system specifically separated organisms based on cell structure, mode of nutrition and other features. Fungi and plants have distinct characteristics which led to their separate classification.
		Formula/Rule: N/A
	2. **Analyze Statement II**: Fungal cell walls are indeed made of chitin, while plant cell walls primarily consist of cellulose. This is a key distinguishing feature between these two groups. Statement II is therefore TRUE.
		Working: Fungal cell walls are characterized by the presence of chitin, while plant cell walls are characterized by cellulose.
		Key Point: The difference in cell wall composition is a critical characteristic for classification.
	3. **Final Step**: Based on the analysis, Statement I is false, and Statement II is true.
		Result: Statement I is false, and Statement II is true.
		Verification: The analysis aligns with the known characteristics of fungi and plants within the five-kingdom classification.
 ## OPTION ANALYSIS
[A] :x: Incorrect. Statement I is false, not true.
[B] ✓: Correct. Statement I is false, and statement II is true.
[C] :x: Incorrect. Statement I is false, statement II is true.
[D] :x: Incorrect. Statement II is true, not false.
 ## LEARNING AIDS
	**Common Mistakes**:
		1. **Misunderstanding the five kingdom system**: Forgetting that the five kingdom system separated organisms based on multiple criteria, including cell wall composition.
		2. **Confusing cell wall components**: Mistaking the composition of fungal and plant cell walls.
	**Quick Tips**:
		1. Remember the key difference: Fungi are heterotrophic with chitin walls; plants are autotrophic with cellulose walls.
		2. Visualize the five kingdoms: Think of how the five kingdoms are separated based on nutrition and cell structure.
