ICSE Class 9 Biology Syllabus Overview
The ICSE Class 9 Biology syllabus explores plant and animal systems, cellular organisation, body movement, respiration, hygiene, diseases, nutrition and ecological impact. Each topic builds conceptual clarity through diagrams, experiments and simple explanations that help learners understand complex biological processes step by step.
The syllabus prepares students for Class 10 by strengthening observation skills, scientific reasoning and awareness of health and environmental issues. Regular practice using the PDFs ensures complete preparation for school assessments and final examinations.
Important Formulas & Key Biology Facts
Biology in Class 9 includes conceptual “formulas”, definitions and key relationships that students should remember. Presented below in list format for quick revision:
- Respiration Equation (Plants): \( \mathrm{C_6H_{12}O_6 + O_2 \rightarrow CO_2 + H_2O + Energy} \)
- Photosynthesis Equation: \( \mathrm{6CO_2 + 6H_2O \xrightarrow{light} C_6H_{12}O_6 + 6O_2} \)
- Classification Basis (Five Kingdoms): Cell type, cell structure, nutrition, reproduction, body organisation.
- Types of Tissues: Epithelial, connective, muscular, nervous (animal) and meristematic & permanent (plant).
- Human Respiratory Equation: \( \mathrm{Glucose + O_2 \rightarrow CO_2 + H_2O + ATP} \)
- Digestive System Flow: Ingestion → Digestion → Absorption → Assimilation → Egestion.
- Joint Types: Fixed, slightly movable, freely movable (synovial).
- Immunity Types: Innate, acquired, active, passive.
- Vectors: Organisms that transmit pathogens (e.g., mosquito, housefly).
- Balanced Diet: Carbohydrates + Proteins + Fats + Vitamins + Minerals + Water + Roughage.
