CBSE Class 11 Biology Important Chapters

In CBSE Class 11 Biology, several chapters provide the basics for understanding important biological concepts needed for the NEET exam. Key chapters include "Cell: The Unit of Life," which explains the structure and function of cells, helping students understand life processes. The chapter on "Biomolecules" introduces important molecules like carbohydrates, proteins, and nucleic acids, which are essential for life. "Plant Physiology" covers how plants function, while "Human Physiology" explains how the human body works. These chapters are not only important for learning biology but also for preparing students for exams like NEET, as they build a strong foundation for success in the subject.
