Question

Choose the correct statement regarding ciliary movement

• A. Longitudinal cilia exhibit synchronous movement.
• B. Transverse cilia exhibit metachronous movement.
• C. Flagellar locomotion is faster than ciliary locomotion.
• D. Cilia bring out the movement of either the organism or the surrounding fluid.

Hint:

Ciliary motion is versatile—locomotion in protozoa, fluid transport in animals.

Answer 1

The Correct Option is D

Cilia are hair-like structures whose coordinated beating results in locomotion (as in Paramecium) or fluid movement (as in the human respiratory tract). They can move the organism or surrounding fluid depending on context.
