All the following statement about inclusion bodies are true except

Options

A. inclusion bodies are not bound by any membrane system.
B. they lie free in the cytoplasm.
C. reserve material in prokaryotic and eukaryotic cells is stored in the form of inclusion bodies.
D. gas vacuoles and phosphate granules are examples of inclusion bodies.

Answer

To solve the question regarding inclusion bodies, we will analyze each statement provided and determine which one is false.

### Step-by-Step Solution:

1. **Understanding Inclusion Bodies**: Inclusion bodies are aggregates of substances within cells, often serving as storage for nutrients or waste products. They can be found in both prokaryotic and eukaryotic cells.

2. **Analyzing Each Statement**:
- **Statement 1**: "Inclusion bodies are not bounded by any membrane system."
- This statement is **true**. Inclusion bodies are typically not surrounded by membranes, distinguishing them from organelles.

- **Statement 2**: "They lie free in the cytoplasm."
- This statement is also **true**. Inclusion bodies are found freely floating in the cytoplasm of the cell.

- **Statement 3**: "Preserved food material in prokaryotic and eukaryotic cells is stored in the form of inclusion bodies."
- This statement is **false**. While inclusion bodies do store food material, they are primarily associated with prokaryotic cells. In eukaryotic cells, food materials are often stored in different forms, such as in organelles like vacuoles.

- **Statement 4**: "Gas vacuoles and phosphate granules are examples of inclusion bodies."
- This statement is **true**. Both gas vacuoles and phosphate granules are recognized examples of inclusion bodies found in various cells.

3. **Identifying the False Statement**: Based on the analysis, the third statement is the only one that is false. Therefore, it is the correct answer to the question.

### Conclusion:
The correct answer is **Statement 3**: "Preserved food material in prokaryotic and eukaryotic cells is stored in the form of inclusion bodies."
