Answer

To determine the number of flagella in Giardia, we can follow these steps:

1. **Identify the Organism**: Recognize that Giardia is a unicellular eukaryotic organism and a known parasite that causes diarrheal diseases.

2. **Understand the Structure**: Giardia has a specific arrangement of flagella. It is important to note that flagella are hair-like structures that aid in movement.

3. **Count the Flagella**: According to the information, Giardia has 4 pairs of flagella. Since each pair consists of 2 flagella, we can calculate the total number of flagella by multiplying the number of pairs by 2.

- Calculation: 4 pairs × 2 flagella per pair = 8 flagella.

4. **Identify the Arrangement**: The flagella are arranged in a specific manner: 4 are lateral, 2 are ventral, and 2 are caudal. This arrangement helps in the movement and attachment of the organism.

5. **Conclusion**: Based on the above information, we conclude that the number of flagella in Giardia is 8.

**Final Answer**: The number of flagella in Giardia is 8.
