CBSE Class 11 Biology Syllabus Practical Syllabus
Biology is not a theoretical subject; it is made up of a variety of practicals and physical experiments. The CBSE Class 11 Biology Syllabus includes a variety of practicals with varying objectives to teach students. The following are the separate lists of experiments and practicals:
List of Experiments
| Experiment No. | Experiment Description |
