Question

**Assertion:** Mitochondria and chloroplasts are considered semi-autonomous organelles.
**Reason:** They have their own DNA and ribosomes but are still dependent on the nucleus for some functions.
Choose the correct option:

K SURESH KUMAR · Accepted Answer

## CORE INFORMATION
✓ **Answer**: A. Both A and R are true and R is the correct explanation of A
## CONCEPT FRAMEWORK
 **Primary Concept**: Semi-autonomous Organelles
 **Related Topics**: Mitochondria, Chloroplasts, Endosymbiotic Theory, Organelle Genetics
 **Prerequisites**: Understanding of cellular organelles and their genetic material.
## SOLUTION PATHWAY
**Given Information**:
	Assertion: Mitochondria and chloroplasts are semi-autonomous.
	Reason: They possess their own DNA and ribosomes but rely on the nucleus for certain functions.
**Method & Steps**:
	1. Evaluate the assertion.
		The assertion is true; mitochondria and chloroplasts have their own DNA and ribosomes, allowing them to produce some of their own proteins, but they are not entirely independent of the nucleus.
	2. Evaluate the reason.
		The reason is also true.  While they have their own genetic material, they still require proteins encoded by nuclear genes for complete functionality.
	3. Determine the relationship between assertion and reason.
		The reason directly explains why mitochondria and chloroplasts are considered semi-autonomous. Their dependence on the nucleus for some functions limits their autonomy.
## OPTION ANALYSIS
A ✓: Both the assertion and reason are correct, and the reason explains the assertion.
B :x: Both are true, but the reason does not fully explain the assertion.
C :x: The assertion is true, but the reason is incorrect.
D :x: The assertion is false, and the reason is true.
## LEARNING AIDS
 **Common Mistakes**: Misunderstanding the concept of semi-autonomy.
 **Quick Tips**: Remember that semi-autonomous organelles have their own DNA and ribosomes but still depend on the nucleus for some essential functions. This is evidence for the endosymbiotic theory.
