Assertion : The endomembrane system includes endoplasmic reticulum (ER), Golgi complex, lysosmes and vacuoles.
Reason : Mitochondria, chloroplast and peroxisomes are not the part of endomembrane system because their functions are coordinated with the same.

Options

A. If both assertion and reason are true amnd reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To analyze the given assertion and reason, we will break down the components 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 collection of membrane-bound organelles that work together to modify, package, and transport lipids and proteins. The ER synthesizes proteins and lipids, the Golgi complex modifies and packages these materials, lysosomes contain digestive enzymes, and vacuoles store substances.

### Step 2: Understand the Reason
The reason provided states that mitochondria, chloroplasts, and peroxisomes are not part of the endomembrane system because their functions are coordinated with the same.

- **Explanation**: Mitochondria and chloroplasts are involved in energy production and photosynthesis, respectively, and they have their own DNA and double membranes. Peroxisomes are involved in lipid metabolism and detoxification. They do not interact with the endomembrane system in the same way as the organelles mentioned in the assertion.

### Step 3: Evaluate the Truth of Both Statements
- The assertion is true because the endomembrane system does include the ER, Golgi complex, lysosomes, and vacuoles.
- The reason is also true in that mitochondria, chloroplasts, and peroxisomes are not part of the endomembrane system. However, the explanation provided in the reason is misleading. The reason does not accurately explain why these organelles are excluded from the endomembrane system.

### Step 4: Conclusion
Both the assertion and reason are true statements, but the reason does not correctly explain the assertion. Therefore, the correct conclusion is that while both statements are true, the reason is not a correct explanation of the assertion.

### Final Answer
Both the assertion and reason are correct, but the reason is an incorrect explanation of the assertion.
