Neuromotor system found in Paramoecium controls

Options

A. Digestion
B. Nervous system
C. Locomotion
D. Osmoregulation.

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks what the neuromotor system in Paramecium controls. The options provided are digestion, nervous system, locomotion, and osmoregulation.

2. **Define the Neuromotor System**: The neuromotor system, also known as the motorium, is a structure in Paramecium that coordinates ciliary movement. It is located near the cytopharynx in ciliates like Paramecium.

3. **Function of Cilia**: Cilia are hair-like structures on the surface of Paramecium that beat in a coordinated manner. This movement is crucial for the organism's ability to move through its aquatic environment.

4. **Role of the Neuromotor System**: The neuromotor system coordinates the movement of cilia. Since the cilia are responsible for the locomotion of Paramecium, the neuromotor system directly influences this movement.

5. **Evaluate the Options**:
- **Digestion**: While Paramecium does digest food, this process is not controlled by the neuromotor system.
- **Nervous System**: Paramecium does not have a nervous system like multicellular organisms; it relies on its neuromotor system for movement.
- **Locomotion**: This is the primary function of the neuromotor system as it coordinates ciliary movement for movement.
- **Osmoregulation**: This process involves maintaining water balance and is not directly controlled by the neuromotor system.

6. **Conclusion**: Based on the understanding of the neuromotor system and its functions, we conclude that the correct answer is that the neuromotor system in Paramecium controls locomotion.

**Final Answer**: The neuromotor system found in Paramecium controls locomotion (Option 3).
