Biology Chapter 5 – Growth and Development (Class 12) for FSC & Entry Test Preparation
Chapter 5, Growth and Development, 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 living organisms grow, develop, and undergo changes from embryonic stages to maturity. Understanding growth and development is essential for studying life processes, physiology, and regulation.

Key Concepts about Growth and Development
The chapter explains the types of growth, including primary and secondary growth in plants and continuous and determinate growth in animals. It covers cell division, differentiation, and the role of meristems in plants. In animals, the chapter discusses developmental stages, hormonal regulation, and factors affecting growth. Processes such as morphogenesis, aging, and regeneration are also explained. Each concept is described with examples, biological significance, and relevance in maintaining life and adaptation. These concepts are highly important for FSC board exams and entry tests like MDCAT, NUMS, AKU, and NUST.
Free Entry Test Preparation
Mastery of growth and development helps students understand cellular processes, regulation of life stages, and developmental biology. 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.
