Question

Which of the following is NOT a characteristic of a eukaryotic cell?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: [D]
## CONCEPT FRAMEWORK
	**Primary Concept**: Characteristics of Eukaryotic Cells
	**Related Topics**: Cell Biology, Prokaryotic vs. Eukaryotic Cells, Cellular Organelles
	**Prerequisites**: Basic understanding of cell structure and types (prokaryotic and eukaryotic)
## SOLUTION PATHWAY
**Given Information**:
	* The question asks for a characteristic that is NOT present in a eukaryotic cell.

**Method & Steps**:
	1.  Recall the defining features of eukaryotic cells.
		Reasoning: Eukaryotic cells are characterized by their complex internal structure.
		Formula/Rule: None applicable for this question.
	2. Compare each option to the known characteristics of eukaryotic cells.
		Working: Eukaryotic cells have a nucleus, membrane-bound organelles, and are generally larger than prokaryotic cells.
		Key Point: Lack of membrane-bound organelles is a defining feature of prokaryotic cells, not eukaryotic.
	3. Identify the option that contradicts the definition of a eukaryotic cell.
		Result:  The option stating 'Lack of membrane-bound organelles' is incorrect for eukaryotic cells.
		Verification: Eukaryotic cells are defined by the presence of membrane-bound organelles.
 ## OPTION ANALYSIS
[A] :x: Presence of a nucleus is a defining characteristic of eukaryotic cells.
[B] :x: Presence of membrane-bound organelles is a key feature of eukaryotic cells.
[C] :x: Eukaryotic cells are typically larger than prokaryotic cells.
[D] ✓: Lack of membrane-bound organelles is a characteristic of prokaryotic cells, not eukaryotic cells.
 ## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Confusing characteristics of prokaryotic and eukaryotic cells. [How to avoid]: Review the key differences between the two cell types.
		2.[Error 2]: Assuming all cells have the same basic structure. [How to avoid]: Understand that prokaryotic cells are simpler while eukaryotic cells are more complex.
	**Quick Tips**:
		1.[Helpful shortcut]: Remember that 'eu' in eukaryotic means 'true' or 'good', referring to the 'true' nucleus and complex structure.
		2.[Memory aid]: Think of eukaryotes as having 'membrane-bound everything' compared to simpler prokaryotes.
