The function of the cilia is to move particles, free cells or mucus in a specific direction. 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.

Explanation:
Ciliated epithelium is a type of tissue that is found in various parts of the body, including the respiratory tract, the fallopian tubes, and the lining of the trachea. The function of ciliated epithelium is to help in the movement of particles.
Assertion (A): Ciliated epithelium helps in movement of particles.
This statement is true. Ciliated epithelium is covered with tiny hair-like structures called cilia. These cilia move in coordinated waves, creating a current that helps to move particles, such as mucus, dust, and bacteria, along the surface of the tissue. This movement is known as ciliary action.
Reason (R): Cilia help in movement.
This statement is also true. Cilia are specialized structures that are found on the surface of certain cells. They are made up of microtubules and can move in a coordinated manner. The movement of cilia is powered by ATP, the energy molecule of the cell. The coordinated movement of cilia allows them to beat in a specific pattern, creating a flow of fluid or particles.
Explanation of the Correct Answer:
The correct answer is option A: Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
The reason (R) correctly explains the assertion (A). Cilia are the structures responsible for the movement in ciliated epithelium. Their coordinated movement creates a flow of fluid or particles, which helps in the movement of particles along the surface of the tissue.
Therefore, both the assertion and the reason are true, and the reason correctly explains the assertion.
