Summary

• Description:

  The MS Word document comprises Form 3 Biology Term 1 2026 Opener Exam with Marking Scheme. The PDF version is also available upon your request. The marking scheme is in a separate document.

  The exam covers a duration of 2 hours and consists of 30 compulsory questions. The paper is designed to assess a wide range of biological concepts through short-answer questions, structured questions, and questions involving diagrammatic analysis. It tests students' understanding of definitions, physiological processes, anatomical adaptations, and experimental procedures across various topics covered in the syllabus up to Form 3.

  The document covers the following topics:

  • Classification (Definition, Binomial nomenclature, Taxon vs Taxonomy)
  • Microscopy (Resolution and magnification calculations)
  • Gas exchange in fish (Gill structure and adaptations)
  • Photosynthesis experiments (Investigation using a bell jar and candle)
  • Transpiration (Role of sunken stomata and types of transpiration)
  • Functions of mammalian blood
  • Digestive system (Adaptations of the ileum for absorption)
  • Cell physiology and organelles (Adaptations of mitochondria)
  • Transport in plants (Adaptations of xylem vessels)
  • Respiration (Oxygen debt)
  • Structure and function of human skin (Sebaceous glands)
  • Homeostasis (Regulation of blood sugar levels)
  • Xerophytic adaptations (Folded leaves and leaves modified to spines)
  • Circulatory system (Differences between arteries and veins, transport of Carbon (IV) Oxide)
  • Structure of the mammalian heart (Diagram labeling and blood flow)
  • Blood groups and transfusion (Compatibility and agglutination)
  • Cell physiology (Osmosis as special diffusion)
  • Nutrition (Indigestible substances in the alimentary canal)
  • Stomatal physiology (Theories of opening and closing)
  • Endocrine system (Functions of ADH and Glucagon)
  • Excretion and Homeostasis (Nephron modifications in desert mammals)
  • Thermoregulation (Role of the hypothalamus)
  • Kidney diseases
  • Photosynthesis (Raw materials, conditions, and chloroplast structure)
  • Functions of plant structures (Phloem, Root hairs, Root cap)
  • Food tests (Starch test procedure and results)
  • Definitions of biological terms (Peristalsis, Emulsification, Excretion, Homeostasis)
  • Liver diseases
