Assertion: Photosynthesis roots are a type of Tap Root System.
Reason: Anoxygenic photosynthesis is performed by photosynthetic roots.

Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

To solve the given assertion and reason question, we will analyze both statements step by step.

### Step 1: Analyze the Assertion
The assertion states: "Photosynthesis roots are a type of Tap Root System."

- **Understanding Photosynthetic Roots**: Photosynthetic roots are specialized roots that can perform photosynthesis. They are typically aerial and adventitious, meaning they grow above the ground and originate from non-root tissue rather than the radical (the embryonic root).
- **Understanding Tap Root System**: A tap root system is characterized by a primary root (the radical) that grows deep into the soil, with smaller lateral roots branching off from it.

**Conclusion for Assertion**: Since photosynthetic roots do not originate from the radical and are not part of the tap root system, this assertion is **false**.

### Step 2: Analyze the Reason
The reason states: "Anoxygenic photosynthesis is performed by photosynthetic roots."

- **Understanding Anoxygenic Photosynthesis**: Anoxygenic photosynthesis is a type of photosynthesis that does not produce oxygen as a byproduct. This process is typically observed in certain bacteria, such as sulfur bacteria, and not in higher plants.
- **Photosynthesis in Plants**: In plants, photosynthesis (whether occurring in leaves or roots) typically produces glucose and oxygen. Therefore, photosynthetic roots in plants do not perform anoxygenic photosynthesis.

**Conclusion for Reason**: Since photosynthetic roots do not perform anoxygenic photosynthesis, this reason is also **false**.

### Final Conclusion
Both the assertion and the reason are false. Therefore, the correct answer is that both the assertion and reason are incorrect.

### Summary of the Solution
- Assertion: False (Photosynthetic roots are not a type of tap root system).
- Reason: False (Photosynthetic roots do not perform anoxygenic photosynthesis).

Thus, the answer is that both the assertion and reason are incorrect.
