Question

Which of the following is not a character of Protista?

D VINOD · Accepted Answer

## CORE INFORMATION
✓ **Answer**: B
## CONCEPT FRAMEWORK
	**Primary Concept**: Characteristics of Kingdom Protista
	**Related Topics**: Classification of living organisms, Eukaryotes, Autotrophs, Heterotrophs
	**Prerequisites**: Basic understanding of biological kingdoms and cellular organization.
## SOLUTION PATHWAY
**Given Information**:
	Characteristics of Protista are being evaluated.
**Method & Steps**:
	1. **Recall the defining features of Protista**:
		Reasoning: Protista are a diverse group of eukaryotic organisms, primarily unicellular, that can be either autotrophic or heterotrophic.
	2. **Analyze each option against these features**:
		Working: 
			A. Eukaryotic cell structure: This is a defining characteristic of Protista.
			B. Presence of complex tissue organization: This is NOT a characteristic of Protista. They are mostly unicellular, and even the multicellular forms lack complex tissue organization.
			C. Mostly unicellular: This is a characteristic of Protista.
			D. Can be autotrophic or heterotrophic: This is a characteristic of Protista.
	3. **Identify the option that does not align with Protista characteristics**:
		Result: Option B, 'Presence of complex tissue organization', is incorrect.
		Verification: Complex tissue organization is a feature of more complex organisms like plants and animals, not Protista.
## OPTION ANALYSIS
[A] ✓: Protista are eukaryotes, meaning their cells have a nucleus and other membrane-bound organelles.
[B] :x: Protista do not have complex tissue organization. They are primarily unicellular, or if multicellular, they exist as simple colonies without specialized tissues.
[C] ✓:  The vast majority of Protista are unicellular organisms.
[D] ✓: Protista exhibit diverse modes of nutrition. Some are autotrophic (like algae), producing their own food through photosynthesis, while others are heterotrophic (like amoeba), obtaining nutrients by consuming other organisms.
## LEARNING AIDS
	**Common Mistakes**:
		1. Confusing Protista with more complex eukaryotes: Remember that while Protista are eukaryotes, they lack the complex tissue organization seen in plants and animals.
		2. Overlooking the diversity within Protista: Protista are a diverse group with varying characteristics. While 'mostly unicellular' is a defining feature, some exceptions exist.
	**Quick Tips**:
		1. Remember the key features of Protista: Eukaryotic, mostly unicellular, autotrophic or heterotrophic, lack complex tissue organization.
		2. Associate Protista with 'simple eukaryotes' to distinguish them from more complex organisms.
