Paraflagellar body of Euglena helps in

Options

A. Locomotion
B. Photoreception
C. Reproduction
D. Osmoregulation

Answer

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

### Step-by-Step Solution:

1. **Identify the Organism**: Recognize that Euglena is a protozoan organism, which is known for its unique features, including the presence of flagella.

2. **Understand the Structure**: The paraflagellar body is a specialized structure found in Euglena. It is a crystalline lamellar structure associated with the organism's sensory functions.

3. **Function of the Flagella**: While the flagella in Euglena are primarily responsible for locomotion, the paraflagellar body serves a different purpose.

4. **Role in Photoreception**: The paraflagellar body is involved in photoreception. It contains photoreceptor structures that help Euglena detect light. This is crucial for the organism as it moves towards light sources for photosynthesis.

5. **Connection to Other Structures**: The paraflagellar body is linked to the sensory neurons and is associated with carotenoid pigments found in the organism. These pigments play a role in light detection.

6. **Conclusion**: Therefore, the paraflagellar body of Euglena primarily helps in photoreception.

### Final Answer:
The paraflagellar body of Euglena helps in photoreception.
