Paraflagellar body occurs in Euglena

Options

A. Near base of flagella
B. Region of union of flagellar branches
C. Area of basal granules
D. On reservoir wall.

Answer

To answer the question regarding the occurrence of the paraflagellar body in Euglena, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Paraflagellar Body**:
- The paraflagellar body is a structure found in certain unicellular organisms, including Euglena. It is associated with the flagellum.

2. **Location of Paraflagellar Body**:
- The paraflagellar body is specifically located near the flagellum. It is a small swelling that is closely associated with the flagellar structure.

3. **Identifying the Correct Option**:
- The options provided are:
- Near the base of flagella
- Region of union of flagellar branches
- Area of basal granules on reservoir wall
- The paraflagellar body is known to be located at the junction of the two flagellar roots, which corresponds to the "region of union of flagellar branches."

4. **Conclusion**:
- Based on the above information, we can conclude that the paraflagellar body occurs in Euglena at the region of union of flagellar branches.

### Final Answer:
The paraflagellar body occurs in Euglena at the region of union of flagellar branches.
