Movement is the temporary or permanent displacement of a body or its parts from its original position. Living beings and parts thereof move in response to stimuli from outside or from within the body. Locomotion, on the other hand, is the displacement of the entire body from one place to another. In this practice set, we have picked some important questions from the chapter Locomotion and movement (class 11th biology) for NEET aspirants. These questions are also helpful for other exams like olympiads, college/university entrance exams, and the Viva-voce exam.
