According to New Education Policy, Sciences is dealt as one common subject up to secondary classes and then as separate disciplines like physics, Chemistry and biology at the Senior Secondary classes. Central Board of Secondary Education in consultation with National Council of Education Research and Training has prepared a new curriculum for theory and practical examinations. This new curriculum well-correlates the theory portion with suitable practicals.
The present Laboratory Manual is an attempt on Biology practicals meant for class XI of Central Board of Secondary Education. All the practicals in this manual are written strictly in accordance with the latest syllabus prescribed by the board. All efforts are made to provide sufficient guidelines, diagrams and procedures actually needed by students and teachers in their practical classes. Viva voce questions are incorporated after each practical for better understanding.
