Which one is widely distributed in a cell

Options

A. DNA
B. RNA
C. Plastids
D. Golgi

Answer

To determine which component is widely distributed in a cell, we can analyze the options provided.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which component is widely distributed within a cell. This means we are looking for a cellular structure or molecule that is present in large quantities or in many locations within the cell.

2. **Evaluating the Options**:
- **Option 1: DNA**: While DNA is essential for genetic information, it is primarily located in the nucleus (in eukaryotic cells) and is not widely distributed throughout the entire cell.
- **Option 2: RNA**: RNA is also crucial for protein synthesis and is found in the nucleus and cytoplasm, but it is not as widely distributed as some other components.
- **Option 3: Plastid**: Plastids are organelles found mainly in plant cells and algae. They are involved in the storage and manufacture of food, and they are indeed widely distributed in plant cells.
- **Option 4: Golgi Apparatus**: The Golgi apparatus is involved in modifying, sorting, and packaging proteins, but it is not as widely distributed as plastids.

3. **Identifying the Correct Answer**: Based on the evaluation, the correct answer is **Option 3: Plastid**. Plastids are double membrane-bound organelles that are widely distributed in plant cells and algae, playing a significant role in food storage and photosynthesis.

4. **Conclusion**: Therefore, the answer to the question "Which one is widely distributed in a cell?" is **Plastid**.
