Assertion : Passive processes like diffusion and osmosis do not require energy.
Reason: Because the plasma membrane is a static membrane.

Options

A. If both Assertion and Reason are true and Reason is correct explanation of Assertion.
B. If both Assertion and Reason are true and Reason is not correct explanation of Assertion.
C. If Assertion is true but Reason is false.
D. If both Assertion and Reason are false.

Answer

To solve the question regarding the assertion and reason, we will break down the statements and analyze them step by step.

### Step 1: Analyze the Assertion
**Assertion:** "Passive processes like diffusion and osmosis do not require energy."

- **Explanation:** Passive processes, such as diffusion and osmosis, occur naturally without the input of energy. In diffusion, substances move from an area of high concentration to an area of low concentration, and in osmosis, water moves across a selectively permeable membrane from a region of lower solute concentration to a region of higher solute concentration. Both processes rely on the concentration gradient and do not require ATP (adenosine triphosphate) or any other form of energy.

### Step 2: Analyze the Reason
**Reason:** "Because the plasma membrane is a static membrane."

- **Explanation:** This statement is incorrect. The plasma membrane is not static; it is dynamic and fluid in nature. The fluid mosaic model describes the plasma membrane as a flexible structure where various proteins float in or on the fluid lipid bilayer. This dynamic nature allows for the movement of molecules in and out of the cell, facilitating processes like diffusion and osmosis.

### Step 3: Determine the Relationship Between Assertion and Reason
- The assertion is true because passive processes do not require energy.
- The reason is false because the plasma membrane is dynamic, not static.

### Conclusion
Based on the analysis:
- The correct answer is that the assertion is true, but the reason is false.

### Final Answer
**Assertion is true, but Reason is false.**
