The non-membrane bound structure that is involved in the synthesis of a non membrane bound organelle is

Options

A. chloroplast
B. mitochondria
C. Nucleolus
D. vacuole

Answer

To solve the question, "The non-membrane bound structure that is involved in the synthesis of a non-membrane bound organelle is," we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding the Question:**
- We need to identify a non-membrane bound structure that synthesizes a non-membrane bound organelle.

2. **Analyzing the Options:**
- **Option 1: Chloroplast**
- Chloroplasts are membrane-bound organelles involved in photosynthesis. They have a double membrane structure. Therefore, this option is incorrect.

- **Option 2: Mitochondria**
- Mitochondria are also membrane-bound organelles, known as the powerhouse of the cell, and they have a double membrane. Hence, this option is incorrect.

- **Option 3: Nucleolus**
- The nucleolus is a non-membrane bound structure found within the nucleus of a cell. It is responsible for synthesizing ribosomes, which are also non-membrane bound organelles. Therefore, this option is correct.

- **Option 4: Vacuole**
- Vacuoles are membrane-bound structures primarily involved in storage and osmoregulation. Thus, this option is incorrect.

3. **Conclusion:**
- After analyzing all the options, the correct answer is **Option 3: Nucleolus**. It is the non-membrane bound structure involved in the synthesis of the non-membrane bound organelle (ribosomes).

### Final Answer:
The non-membrane bound structure that is involved in the synthesis of a non-membrane bound organelle is the **Nucleolus**.
