The main function of the cilia is to move particles. It is present in inner surfaces of some hollow organs such as fallopian tubes, bronchioles and small bronchi and help in movement of the particles present there. Thus the function of ciliated epithelium (as it possesses cilia) is the movement of particles.

Assertion: Ciliated epithelium helps in movement of particles.
Reason: Cilia help in movement.
The correct answer is option 'A', which states that both the assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
Explanation:
Ciliated epithelium is a type of tissue that lines various organs and structures in the body. It is characterized by the presence of cilia, which are hair-like structures present on the surface of the cells. These cilia have a specific function in facilitating movement.
Ciliated Epithelium
- Ciliated epithelium is found in various parts of the respiratory system, including the trachea and bronchi, as well as in the fallopian tubes and parts of the reproductive system.
- The cilia on the surface of the cells in ciliated epithelium are capable of beating in a coordinated manner.
- The coordinated movement of cilia creates a wave-like motion, which helps in the movement of particles along the surface of the epithelium.
Function of Cilia
- The primary function of cilia is to move particles in a specific direction.
- In the respiratory system, the cilia in the trachea and bronchi help to move trapped particles, such as dust, mucus, and microorganisms, out of the airways.
- This movement of particles by cilia is known as mucociliary clearance and is an important defense mechanism of the respiratory system.
- Similarly, in the female reproductive system, the cilia in the fallopian tubes help to move the egg from the ovary towards the uterus.
Explanation of the Reason
- The reason provided in the question is that cilia help in movement.
- This reason is correct because the movement of particles facilitated by cilia is a well-known function of ciliated epithelium.
- The coordinated beating of cilia creates a directional flow, which helps in the movement of particles along the surface of the epithelium.
Conclusion
In conclusion, the assertion that ciliated epithelium helps in the movement of particles is true, and the reason provided, which states that cilia help in movement, is the correct explanation for this assertion.
