CBSE Class 10 Science Important Diagrams 2025–26 (Physics, Chemistry & Biology)

CBSE Class 10 Science Important Diagrams 2025–26 are a crucial part of board exam preparation. Every year, several questions are asked directly or indirectly from labelled diagrams in Biology, Physics, and Chemistry. Students preparing for the CBSE 10th Science Exam 2026 must practice all important diagrams thoroughly to score high marks.

This post covers important diagrams for CBSE Class 10 Science, including Biology diagrams, Physics ray diagrams, and Chemistry atomic structure diagrams, which are frequently asked in board examinations.

CBSE 10th Science Exam 2025: Important Diagrams for Biology

Important diagrams for CBSE Class 10 Biology play a major role in Life Processes, Control and Coordination, and Reproduction chapters. These diagrams are often asked for labelling, structure explanation, and short answers.

Biology Diagrams (Life Processes & Control)

 Nephron: Structure and function

 Neuron (Nerve Cell): Dendrites, cell body, axon

 Reflex Arc: Pathway of nerve impulse

 Human Heart: Internal structure (double circulation)

 Human Digestive System: Organs involved

 Human Respiratory System: Trachea, bronchi, alveoli

 Flower (LS): Sepals, petals, stamens, pistil

 Cross Section of a Leaf: Stomata, guard cells, epidermal layers

 Endocrine Glands: Pituitary, Thyroid, Male & Female reproductive systems

 Nutrition in Amoeba: Phagocytosis

These important diagrams for CBSE Class 10 Biology are commonly tested and should be practiced neatly with correct labels.

 CBSE Class 10th Science: Important Physics Diagrams

CBSE Class 10th Science Physics diagrams mainly focus on Light and Electricity chapters. Ray diagrams and electrical devices are frequently asked in board exams.

 Physics Diagrams (Light & Electricity)

 Ray Diagrams for spherical mirrors (concave and convex)

 Ray Diagrams for lenses (concave and convex)

 Human Eye: Structure and defects (Myopia and Hypermetropia) with correction lenses

 Electric Motor: Principle and working

 Electric Generator: Principle and working

 Electric Circuit: Symbols, series and parallel connections

Practicing Physics ray diagrams for Class 10 board exam helps students score full marks in numerical and diagram-based questions.

 CBSE Class 10 Science Important Chemistry Diagrams

Important diagrams for CBSE Class 10 Science Chemistry mainly come from the Structure of Atom chapter. These diagrams are simple but very scoring.

 Chemistry Diagrams

 Bohr’s Model of Atom: Electrons in K, L, and M shells

 Atomic Structure: Protons, neutrons, and electrons

 Atomic Structure (Bohr’s Model): Draw atom with nucleus at centre containing protons (positive charge) and neutrons (no charge)

These diagrams are often asked for labelling and explanation in board exams.
