Locomotory organelles in the protista are

Options

A. Flagella
B. Cilia
C. Pseudopodia
D. All of these

Answer

To answer the question about the locomotory organelles in the Protista, we can break down the information as follows:

### Step-by-Step Solution:

1. **Understanding Protista**:
- Protista is a kingdom that includes all types of unicellular eukaryotes. This means that organisms in this kingdom are made up of a single cell and have a defined nucleus.

2. **Identifying Locomotory Organelles**:
- In the kingdom Protista, there are three main types of locomotory organelles:
- **Flagella**: These are long, whip-like structures that help in movement.
- **Cilia**: These are short, hair-like structures that cover the surface of some protists and assist in locomotion.
- **Pseudopodia**: Also known as "false feet," these are temporary projections of the cell that help in movement and feeding.

3. **Examples of Protists with Locomotory Organelles**:
- **Flagella**: Found in organisms like **Euglena**, which uses flagella for swimming.
- **Cilia**: Present in **Paramecium**, which uses cilia for movement.
- **Pseudopodia**: Found in **Amoeba**, which uses pseudopodia to move and engulf food.

4. **Conclusion**:
- Therefore, the locomotory organelles in Protista include flagella, cilia, and pseudopodia. The correct answer to the question is that all of these organelles are present in various protists.

### Final Answer:
The locomotory organelles in Protista are flagella, cilia, and pseudopodia.
