Biology is the branch of science that deals with life and living organisms. The main objective of Biology is to understand the various processes taking place inside any living organism. It includes the formation of cells, composition of cells and formation of tissues. It also reflects on the changes occurring in human body. It depicts how the living and non living components interact with each other.

Here we will cover the various topics regarding Biology for Class 9. The concepts that are mastered in the lower classes help us to crack many entrance examinations like NEET, AIIMS, AIPMT, UPSC etc. At ABHYASONLINE.IN you can master the concepts at your own learning pace. It provides conceptual testing with analytical reports identifying the weak, moderate and strong concepts. We, at ABHYASONLINE.IN believe that, if the weak concepts are timely identified and improved, then every student can achieve their goals in life. Follow the links below to understand and master each and every concept of various topics in Biology along with video lectures.
