Motility is by flagella (or) Cilia in

Options

A. Monera
B. Protista
C. Fungi
D. Animalia

Answer

To determine which group of organisms exhibits motility through flagella or cilia, we can analyze the options provided: Monera, Protista, Fungi, and Animalia.

### Step-by-Step Solution:

1. **Understanding Flagella and Cilia**:
- Flagella are long, tail-like structures that help in movement.
- Cilia are short, hair-like structures that also assist in locomotion.

2. **Analyzing Each Option**:
- **Monera**: This group includes prokaryotic organisms like bacteria. While some bacteria have flagella for movement, they do not possess cilia. Therefore, this option is partially correct but does not include both flagella and cilia.
- **Protista**: This group consists of eukaryotic unicellular organisms. Many protists have both flagella and cilia for movement. This makes Protista a strong candidate for the correct answer.
- **Fungi**: Fungi are generally non-motile and do not have flagella or cilia. They absorb nutrients from their surroundings and do not exhibit movement like the other groups. Thus, this option is incorrect.
- **Animalia**: While animals are motile, their movement is primarily facilitated by limbs, fins, or wings rather than flagella or cilia. Therefore, this option is also incorrect.

3. **Conclusion**:
- Based on the analysis, the only group that exhibits motility through both flagella and cilia is **Protista**.

### Final Answer:
Motility is by flagella or cilia in **Protista**.
