CBSE Class 10 Science Exam 2026: Important Keywords and Diagrams Examiners Expect in Biology Answers

Scoring well in the Biology section of the CBSE Class 10 Science Exam 2026 is not only about writing long answers. Examiners usually look for correct keywords, clear explanations, and well-labeled diagrams. If students include these elements in their answers, it becomes easier for the examiner to understand their knowledge, which can help them secure better marks.

Biology answers in the board exam should be short, precise, and written using the correct scientific terms. Using the right keywords shows that the student understands the concept properly and has studied the chapter carefully. Along with keywords, drawing neat diagrams with proper labeling can also make a big difference in the overall score.
