Support and Movement is an important chapter of Class 10 Biology that explains how organisms maintain their shape and move from one place to another. This chapter covers the skeletal system, types of skeletons, structure and function of bones and joints, and the role of muscles in movement. This post includes Class 10 Biology Chapter 4 MCQs prepared according to the Punjab and Sindh Board syllabus to help students revise key concepts for examinations.
