In Vorticella during binary fission plane of division passes along

Options

A. Any plane of organism
B. Transverse axis of organism
C. Longitudinal axis of body
D. At an angle to transverse axis of body

Answer

### Step-by-Step Solution:

1. **Understanding Binary Fission**:
- Binary fission is a type of asexual reproduction where a single parent cell divides into two equal daughter cells. This process involves the duplication of the genetic material followed by the division of the cytoplasm.

2. **Identifying the Organism**:
- The organism in question is Vorticella, which is a genus of single-celled eukaryotic organisms, commonly found in freshwater environments like ponds and lakes.

3. **Analyzing the Division Process**:
- In Vorticella, during binary fission, the division occurs along a specific plane. It is important to identify the orientation of this division.

4. **Determining the Plane of Division**:
- The key detail is that Vorticella divides along the longitudinal axis. This means that the organism splits lengthwise, resulting in two daughter cells that are oriented in the same direction as the original cell.

5. **Evaluating the Options**:
- The options provided are:
1. Any plane of the organism
2. Longitudinal plane
3. Transverse axis
4. Longitudinal axis of the body
5. At an angle to transverse axis of the body
- Based on our understanding, the correct option is the one that states the division occurs along the longitudinal axis of the body.

6. **Conclusion**:
- Therefore, the correct answer is that during binary fission in Vorticella, the plane of division passes along the longitudinal axis of the body.

### Final Answer:
The plane of division in Vorticella during binary fission passes along the longitudinal axis of the body.
