A multicelluar ortganism possesses

Options

A. Differentiated cells
B. Undifferentiated cells
C. Dedifferentiated cells
D. All the above

Answer

### Step-by-Step Solution:

1. **Understanding Multicellular Organisms**:
- Multicellular organisms are composed of multiple cells that work together to perform various functions. These organisms can be plants, animals, fungi, etc.

2. **Differentiated Cells**:
- In multicellular organisms, cells can become specialized through a process called differentiation. This means that certain cells take on specific roles (e.g., muscle cells, nerve cells, etc.) to contribute to the organism's overall function.

3. **Undifferentiated Cells**:
- Some cells remain undifferentiated, meaning they have not yet specialized. These are often referred to as stem cells. They have the potential to differentiate into various types of cells as needed by the organism.

4. **De-differentiated Cells**:
- De-differentiation is a process where specialized cells revert to a less specialized state. This can occur in certain conditions, allowing these cells to regain the ability to differentiate into other cell types.

5. **Conclusion**:
- Since multicellular organisms possess all three types of cells—differentiated, undifferentiated, and de-differentiated—the correct answer to the question is "all of the above."

### Final Answer:
A multicellular organism possesses differentiated cells, undifferentiated cells, de-differentiated cells, and thus the answer is **all of the above**.
