In Paramecium beating of cilia is controlled by

Options

A. Neuromotor system
B. Kinety
C. Kinetosome
D. Pellicle.

Answer

To answer the question "In Paramecium, beating of cilia is controlled by," we will analyze the options provided and determine the correct answer step by step.

### Step-by-Step Solution:

1. **Understanding Cilia in Paramecium**:
- Paramecium is a unicellular organism that is covered with numerous cilia (approximately thousands). These cilia beat rhythmically to help the organism move and to sweep food into its oral groove.

2. **Analyzing the Options**:
- The options given are:
- A) Neuromotor system
- B) Kinetes
- C) Kinetosome
- D) Pellicle

3. **Evaluating Each Option**:
- **Option A: Neuromotor System**: This system controls the movement of cilia through a group of contractile fibrils. It is responsible for the rhythmic beating of cilia and overall body movement. This option is likely correct.
- **Option B: Kinetes**: Kinetes refer to the body of somatic cilia that lie in a row. They do not control the beating of cilia, making this option incorrect.
- **Option C: Kinetosome**: This is a structure associated with cilia but does not control their beating. Therefore, this option is also incorrect.
- **Option D: Pellicle**: The pellicle is the outer covering of Paramecium and does not play a role in the control of cilia movement. Thus, this option is incorrect.

4. **Conclusion**:
- After evaluating all options, the correct answer is **A) Neuromotor system**, as it is responsible for controlling the beating of cilia in Paramecium.

### Final Answer:
The beating of cilia in Paramecium is controlled by the **neuromotor system**.
