Diagrams carry up to 5 marks each in the Class 10 science question paper. That is not something you can revise the night before and expect full marks.<\/p>\n

CBSE Class 10 science question paper examines diagrams in Biology, Physics, and Chemistry, every year, without exception. By knowing precisely which ones you must prepare and how to draw them properly, you are picking up marks that most students leave on the table.<\/p>\n

Here is the subject-wise list of important diagrams for class 10 science, straight from Aakash’s pattern analysis of previous year papers, of every diagram you must be ready to draw before the exam.<\/p>\n

Biology Diagrams in the Class 10 Science Question Paper<\/strong><\/h2>\n

In Biology, diagrams are not supporting material. They are the answer. The <\/span>CBSE syllabus for class 10<\/b> science<\/b> allocates 25 marks to the World of Living unit, and diagram-based questions show up in nearly every board paper from this section.<\/span><\/p>\n

These are the non-negotiable Biology diagrams for class 10 science:<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n
Diagram Topic<\/b><\/td>\nWhat to Focus On (Board Exam Expectation)<\/b><\/td>\n<\/tr>\n
Human Digestive System<\/b><\/a><\/td>\nLabel all organs, including villi; completeness is checked<\/span><\/td>\n<\/tr>\n
Human Heart<\/b><\/a><\/td>\nShow all four chambers, valves, and direction of blood flow<\/span><\/td>\n<\/tr>\n
Human Brain<\/b><\/a><\/td>\nClearly separate and label cerebrum, cerebellum, and medulla<\/span><\/td>\n<\/tr>\n
Human Eye<\/b><\/a><\/td>\nLabel parts (cornea, lens, retina, optic nerve, iris, etc.)<\/span><\/td>\n<\/tr>\n
Nephron<\/b><\/a><\/td>\nStructure questions are often paired with function; know both<\/span><\/td>\n<\/tr>\n
Reflex Arc<\/b><\/a><\/td>\nShow nerve pathway from receptor to effector; name each component<\/span><\/td>\n<\/tr>\n
Structure of a Flower<\/b><\/a><\/td>\nLabel anther, stigma, ovary, and petals; frequently asked in the reproduction chapter<\/span><\/td>\n<\/tr>\n
Food Chain and Food Webs<\/b><\/a><\/td>\nShow flow of energy and feeding relationships; arrows and correct trophic levels matter.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Here is what we see at Aakash after training lakhs of students: a messy diagram with unlabelled parts can cost you 2 out of 5 marks even when the written explanation is correct. Draw to perform, not just to understand.<\/span><\/p>\n
