ICSE Class 8 Biology Syllabus Overview
The ICSE Class 8 Biology syllabus introduces core biological ideas such as cellular functions, plant physiology, reproduction, nutrition, circulation, coordination, health, pollution and environmental conservation. These topics build scientific understanding and prepare students for higher-level Biology in Class 9 and 10.
Each chapter supports learning through diagrams, examples, activities and structured exercises. This ensures that students develop observation skills, analytical thinking and conceptual clarity.
Important Biology Formulas & Key Concepts
Biology at this level includes essential definitions, equations and ideas that students must remember. Key concepts include:
- Photosynthesis Equation: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
- Respiration Equation: Glucose + Oxygen → Carbon dioxide + Water + Energy
- Xylem Function: Conducts water and minerals in plants.
- Phloem Function: Transports prepared food in plants.
- Germination Requirements: Water, oxygen, suitable temperature.
- Pollution Types: Air, water, soil, noise.
- Hormones: Chemical messengers controlling growth and metabolism.
- Asexual Reproduction: Binary fission, budding, spore formation.
- Sexual Reproduction: Fusion of male and female gametes.
- Balanced Diet: Carbohydrates, proteins, fats, vitamins, minerals, water and roughage.
- Microorganisms: Useful (yeast, bacteria) and harmful (pathogens).
