Assertion :- Endomembrane system includes ER, golgi complex, lysosome and vacuoles.
Reason:- Their functions are coordinated.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are false.

Answer

To analyze the assertion and reason provided in the question, we can break down the information step by step:

### Step 1: Understand the Assertion
The assertion states that the endomembrane system includes the endoplasmic reticulum (ER), Golgi complex, lysosomes, and vacuoles.

**Explanation**:
- The endomembrane system is a network of membranes within the cell that works together to modify, package, and transport lipids and proteins.
- The components mentioned (ER, Golgi complex, lysosomes, and vacuoles) are indeed part of this system.

### Step 2: Understand the Reason
The reason states that the functions of these components are coordinated.

**Explanation**:
- The functions of the endoplasmic reticulum, Golgi apparatus, lysosomes, and vacuoles are indeed coordinated.
- For instance, the ER synthesizes proteins and lipids, which are then transported to the Golgi apparatus for modification and packaging.
- The Golgi apparatus then sends these proteins to their final destinations, including lysosomes for waste processing or secretion outside the cell.

### Step 3: Evaluate the Relationship Between Assertion and Reason
Now, we need to determine if the reason provided is a correct explanation of the assertion.

**Explanation**:
- Since the assertion is true (the components are part of the endomembrane system) and the reason is also true (their functions are coordinated), and the reason explains why the assertion is true, we can conclude that both are correct and the reason is indeed the correct explanation of the assertion.

### Conclusion
Both the assertion and the reason are true, and the reason correctly explains the assertion.

### Final Answer
The correct option is: **Both assertion and reason are true, and reason is the correct explanation of assertion.**
