Chromonemata embedded in a :–

Options

A. Stroma
B. Matrix
C. Sugar
D. Mucilage

Answer

To answer the question "Chromonemata embedded in a:", we need to analyze the options provided and understand the context of chromonemata.

### Step-by-Step Solution:

1. **Understanding Chromonemata**:
- Chromonemata are the thread-like structures that make up chromosomes. They are coiled filaments that contain DNA, which carries genetic information.

2. **Analyzing the Options**:
- **Option 1: Stroma**:
- Stroma is the fluid found in chloroplasts that surrounds the thylakoids. It is not related to chromonemata. Thus, this option is incorrect.
- **Option 2: Matrix**:
- The matrix refers to the material in which chromonemata are embedded within the chromosome. This is the correct option as chromonemata are indeed embedded in the chromosomal matrix.
- **Option 3: Sugar**:
- Sugar is a type of carbohydrate and does not have a direct relationship with chromonemata. Thus, this option is incorrect.
- **Option 4: Mucilage**:
- Mucilage is a gelatinous substance produced by plants, primarily for water and food storage. It does not relate to chromonemata, making this option incorrect as well.

3. **Conclusion**:
- After analyzing all options, the correct answer is **Option 2: Matrix**. Chromonemata are embedded in the chromosomal matrix.

### Final Answer:
Chromonemata are embedded in a **Matrix**.
