CBSE Biotechnology Syllabus for Class 11: Biotechnology is an important subject for science stream students in Class 11. It is an elective course that can be taken along with other subjects to gain knowledge and grades. Students who have an interest in the field of life sciences opt for this subject. The curriculum of CBSE Class 11 Biotechnology is not very huge as it aims to give basic knowledge to students to form a foundation for the future. The curriculum starts with an overview of Biotechnology that deepens a little in successive units. To understand the complete course structure and unit-wise syllabus check this article.
