Assertion :- Endoplasmic reticulum leads to dual compartmentalisation of cell cytoplasm.
Reason:- Due to tubular organisation of ER, it creates luminal and extraluminal compartments of cytoplasm

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 given assertion and reason, we can break down the solution into the following steps:

### Step 1: Understand the Assertion
The assertion states that "Endoplasmic reticulum leads to dual compartmentalization of cell cytoplasm."
- The endoplasmic reticulum (ER) is a network of membranes within the cell that plays a crucial role in the compartmentalization of the cytoplasm. It divides the cytoplasm into two distinct compartments.

**Hint:** Think about how the structure of the ER contributes to the organization of cellular components.

### Step 2: Understand the Reason
The reason provided is "Due to tubular organization of ER, it creates luminal and extraluminal compartments of cytoplasm."
- The ER has a tubular structure that forms two compartments:
- The **luminal compartment** is the space inside the ER.
- The **extraluminal compartment** is the space outside the ER, within the cytoplasm.

**Hint:** Consider how the physical structure of the ER influences the spaces it creates within the cell.

### Step 3: Analyze the Relationship
Now, we need to determine if the reason correctly explains the assertion.
- The assertion is true because the ER does lead to dual compartmentalization.
- The reason is also true because the tubular organization of the ER does indeed create these two compartments.

**Hint:** Reflect on whether the reason directly supports the assertion in a logical way.

### Step 4: Conclusion
Since both the assertion and reason are true, and the reason provides a correct explanation for the assertion, we conclude that the correct option is:
- Both assertion and reason are true, and the reason is the correct explanation of the assertion.

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