Assertion : The role of chlorophyll in photosynthesis is absorption of light and photolysis of water.
Reason : The function of solar energy is assimilation of `CO_2`

Options

A. If both Assertion and Reason are true and Reason is correct explaination of Assertion.
B. If both Assertion and Reason are true but 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 analyze the given statements, we will break down the assertion and the reason step by step.

### Step 1: Understand the Assertion
The assertion states: "The role of chlorophyll in photosynthesis is absorption of light and photolysis of water."
- **Explanation**: Chlorophyll is the green pigment found in plants that plays a crucial role in photosynthesis. It absorbs light energy, primarily from the blue and red wavelengths of sunlight. This energy is essential for the process of photosynthesis, where it helps in splitting water molecules (photolysis) into oxygen, protons, and electrons.

### Step 2: Understand the Reason
The reason states: "The function of solar energy is assimilation of CO₂."
- **Explanation**: While solar energy is indeed used in photosynthesis, its primary role is not just the assimilation of carbon dioxide (CO₂). Instead, solar energy is used to convert CO₂ and water into glucose and oxygen through the overall process of photosynthesis. The assimilation of CO₂ occurs during the Calvin cycle, which is a part of the photosynthesis process but not the sole function of solar energy.

### Step 3: Evaluate the Truth of Each Statement
- **Assertion**: True. Chlorophyll absorbs light and facilitates the photolysis of water.
- **Reason**: False. Solar energy is used in photosynthesis, but its function is broader than just the assimilation of CO₂.

### Step 4: Conclusion
Based on the evaluations:
- The assertion is true, while the reason is false. Therefore, the correct answer is that the assertion is true and the reason is false.

### Final Answer
Assertion is True and Reason is False.
