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 the statements provided about them and identify the one that is incorrect.

### Step-by-Step Solution:

1. **Understanding Inclusion Bodies**:
- Inclusion bodies are aggregates of substances within a cell that are not bound by a membrane. They can store various materials such as nutrients or waste products.

2. **Characteristics of Inclusion Bodies**:
- They are not surrounded by any membrane system.
- They are found freely in the cytoplasm of both prokaryotic and eukaryotic cells.

3. **Examples of Inclusion Bodies**:
- Common examples include phosphate granules, glycogen granules, and gas vacuoles. These can be found in prokaryotic cells (like bacteria) and some eukaryotic cells.

4. **Analyzing the Statements**:
- The statements provided in the question likely include:
a. Inclusion bodies are not bound by any membrane system.
b. They lie free in the cytoplasm.
c. They store reserve material in prokaryotic and eukaryotic cells.
d. They are only found in prokaryotic cells.

5. **Identifying the Incorrect Statement**:
- The first two statements about inclusion bodies being membrane-less and lying freely in the cytoplasm are true.
- The third statement about storing reserve material in both prokaryotic and eukaryotic cells is also true.
- The fourth statement, which claims that inclusion bodies are only found in prokaryotic cells, is incorrect because inclusion bodies can also be found in eukaryotic cells.

### Conclusion:
The incorrect statement about inclusion bodies is that they are only found in prokaryotic cells.
