Ciliated protozoans: These are aquatic, actively moving organisms because of the presence of thousands of cilia. They have a cavity (gullet) that opens to the outside of the cell surface. The coordinated movement of rows of cilia causes the water laden with food to be steered into the gullet. Example: Paramoecium.
Assertion (A): Ciliated protozoans can capture food particles from their aquatic environment. Reason (R): The coordinated movement of rows of cilia creates water currents that steer food-laden water into the gullet.
