The condition where filaments and anthers are fused throughout the entire length is

Options

A. Synandrous
B. Gynandrous
C. Protandrous
D. Syngenesious

Answer

To solve the question regarding the condition where filaments and anthers are fused throughout their entire length, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a specific condition in flowering plants where the filaments (the stalks that support the anthers) and the anthers (the pollen-producing part) are fused together.

2. **Analyze the Options**: The options provided are:
- **Synandrous**
- **Gynandrous**
- **Protandrous**
- **Syngenous**

3. **Define Each Option**:
- **Synandrous**: This term refers to a condition where the anthers and filaments are fused together to form a single structure.
- **Gynandrous**: In this condition, the anthers are fused with the gynoecium (the female reproductive part of the flower).
- **Protandrous**: This term describes a situation where the male reproductive structures mature before the female structures in a flower.
- **Syngenous**: In this case, the anthers are fused, but the filaments remain free from each other.

4. **Identify the Correct Option**: Based on the definitions:
- The question specifies that both filaments and anthers are fused throughout their entire length. This matches the definition of **Synandrous**.

5. **Conclusion**: Therefore, the correct answer to the question is **Synandrous**.

### Final Answer:
The condition where filaments and anthers are fused throughout the entire length is **Synandrous**.
