CBSE Class 11 Biotechnology Syllabus: In Class 11, biotechnology is a crucial topic for students in the science stream. To improve your knowledge and grades, you can study this elective course in addition to other disciplines. Students choose this course because they are interested in the living sciences. The CBSE Class 11 Biotechnology curriculum is not very extensive because its goal is to provide students with fundamental knowledge that will serve as a basis for their future. The first unit of the curriculum provides an overview of biotechnology, which is then slightly expanded upon in later units. See this article for a comprehensive overview of the course structure and unit-by-unit syllabus. Additionally, download the paper design and practical list for the 2025–2026 school year. According to the syllabus, the Bio-Technology subject is off 100 marks for the 2025–2026 academic year, which includes a 80-mark theory component and a 20-mark practical assessment. The syllabus outlines the chapters and units of study that the students will be studying during the session.
