Biology Chapter 2 – Support and Movement (Class 12) for FSC & Entry Test Preparation
Chapter 2, Support and Movement, is an important topic for Class 12 students preparing for FSC board exams and medical/engineering entry tests like MDCAT, NUMS, AKU, NUST, ECAT, and UET. This chapter explains how organisms maintain their shape, structural integrity, and movement. Understanding support and movement is essential for studying the skeletal and muscular systems in animals and structural adaptations in plants.

Key Concepts about Support and Movement
The chapter explains the types of support systems in animals, including the exoskeleton, endoskeleton, and hydrostatic skeleton. It also covers the human skeletal system, types of bones, joints, and their functions in providing movement and protection. The chapter further discusses the muscular system, types of muscles, and the mechanism of muscle contraction. In plants, support structures such as cell walls, turgor pressure, and specialized tissues like collenchyma and sclerenchyma are explained. Each concept is described with examples, structural details, and significance in maintaining stability and movement. These concepts are highly important for FSC board exams and entry tests like MDCAT, NUMS, AKU, and NUST.
Free Entry Test Preparation
Mastery of support and movement helps students understand structural adaptations, biomechanics, and the interaction of skeletal and muscular systems. PLS Academy provides practice questions, solved past papers, and chapter-wise MCQs to help students revise these topics effectively. Regular study of this chapter improves problem-solving skills, conceptual clarity, and exam performance, ensuring students are well-prepared for both board exams and competitive entry tests.
JazakAllah.
