ICSE Class 10 Biology – Free PDF Download 2026-27

ICSE Class 10 Biology is the board-level life science subject — covering human physiology, ecology, and genetics for Class 10 students. It is conducted by the Council for the Indian School Certificate Examinations (CISCE), which sets one of India’s most detailed and application-focused science curricula. The subject spans ten chapters and is assessed in the annual ICSE board examination, which is recognised by universities across India and abroad. On this page, you will find chapter-wise notes, Selina Concise solutions, previous year question papers, and completely free PDF study materials for 2026-27.

ICSE Class 10 Biology Syllabus Overview

The ICSE Class 10 Biology syllabus is prescribed by CISCE and is divided into ten chapters that span cell biology, plant physiology, human anatomy, genetics, and environmental science. The board emphasises diagram-based answers and application of concepts, which distinguishes it from other national boards. Students are assessed through a written theory paper that carries significant weight in the final board result.

The following chapters form the core of the Class 10 Biology programme under the ICSE board:

• Chapter 2 — Structural organisation of plant and animal tissues, with diagram-based questions appearing frequently in board papers.
• Chapter 3 — Absorption by roots, covering osmosis, diffusion, and active transport — concepts tested both theoretically and diagrammatically.
• Chapter 4 — Transpiration and its significance to plant physiology; a consistent source of short-answer marks.
• Chapter 5 — Photosynthesis, including the light and dark reactions and experiments that CISCE examiners favour every year.
• Chapter 6 — Chemical coordination in plants and animals, covering hormones and their roles.
• Chapter 7 — The circulatory system in humans, with detailed diagrams of the heart required in exams.
• Chapter 8 — The excretory system, focusing on nephron structure and urine formation.
• Chapter 9 — The nervous system and sense organs, including reflex arcs and the human brain.
• Chapter 10 — Genetics — Mendelian laws, monohybrid and dihybrid crosses, and inheritance patterns tested in structured questions.

CISCE also includes Chapter 1 as an introductory unit on basic biology concepts that supports the remaining chapters. Practising diagrams alongside theory reading is the single most effective strategy for scoring well in this paper.

Recommended Books for ICSE Biology Class 10

Choosing the right ICSE Class 10 Biology book is critical because the CISCE examination is closely aligned with specific publishers. The most widely recommended title is Selina Concise Biology for Class 10, whose chapter structure mirrors the official CISCE syllabus exactly. Frank Brothers and S.Chand also publish supplementary guides that are useful for additional practice questions.

Here is a quick guide to the most trusted Biology resources for ICSE board students:

• Selina Concise Biology (Class 10) — The primary textbook aligned chapter-by-chapter with CISCE guidelines; solutions are available as free PDFs on this page.
• Frank Brothers Biology — Offers additional objective and short-answer questions useful for self-testing before board examinations.
• S.Chand Biology for ICSE — Provides detailed explanations of genetics and physiology chapters that students often find challenging.
• CISCE Specimen Papers — Official sample papers released by the council; practising these is non-negotiable for exam preparation.

Chapter-wise Notes and Exam Strategy for ICSE Biology

Well-organised ICSE Class 10 Biology notes save revision time and improve retention during the hectic pre-board period. The notes available on icseboard.org are structured to match the CISCE marking scheme, with key definitions, labelled diagrams, and comparison tables for topics such as mitosis vs meiosis and aerobic vs anaerobic respiration.

Follow this evidence-based revision approach to maximise your board score:

1. Read the Selina chapter first to build conceptual understanding before attempting any questions.
2. Draw and label every diagram in the chapter — CISCE allocates dedicated marks to diagram accuracy and labelling.
3. Summarise definitions into a single A4 sheet per chapter; CISCE frequently asks for precise scientific definitions in two to three sentences.
4. Solve previous year questions chapter-wise to identify the question types CISCE repeats across sessions.
5. Attempt the specimen paper under timed conditions at least two weeks before the board exam.

Genetics (Chapter 10) and the Nervous System (Chapter 9) are the two chapters that consistently carry the highest proportion of five-mark and eight-mark questions in ICSE board papers. Allocate proportionally more revision time to these units.

ICSE Class 10 Biology Question Papers and Sample Papers

ICSE Class 10 Biology previous year question papers are the most reliable indicator of exam pattern, difficulty level, and topic weightage. CISCE has maintained a consistent structure over the past decade — Section A contains compulsory short questions, while Section B offers choice-based long-form questions carrying higher marks.

ICSE Class 10 Biology sample papers issued by CISCE mirror the actual board paper format and are updated each year to reflect any syllabus revisions. Solving at least five to six previous year papers alongside the current specimen paper is the standard recommendation from experienced ICSE Biology teachers.

The icseboard.org collection includes 48 verified resources across books, question papers, sample papers, and solutions — all freely downloadable as PDFs. Each paper is labelled by year and type so students can plan a structured revision timetable without confusion.

ICSE Board Biology vs CBSE Science: Key Differences

Parents and students often compare ICSE board Class 10 Biology with the CBSE Science syllabus before choosing a board. The two curricula differ significantly in depth, assessment style, and publisher alignment. The table below summarises the most important distinctions:

The standalone Biology paper in ICSE gives students more focused preparation time compared to the combined Science paper in CBSE. This depth is one reason ICSE Biology graduates often find undergraduate life science courses more accessible.
