CBSE Syllabus for Class 9 Biology 2021-2022 Exam

 

CBSE Class 9 Biology syllabus is included in the Science syllabus only. But, every student needs to identify the topics under each stream, that is Physics, Chemistry and Biology. This will help them identify their interests and decide which subjects they want to study in higher classes. Class 9 Biology syllabus includes three units: Unit II - Organization in the Living World and Unit IV - Our Environment and Unit V - Food; Food Production. All these three units comprise 30 Marks out of the 80 Marks of the theory examination. This means, if you want to score maximum marks in the theory paper, you must study biology chapters carefully and prepare them well. 

 

The three units of the CBSE Class 9 Biology syllabus include topics like the cell which is also known as the basic unit of life, tissues, organs and organ systems. You will be studying the biological diversity in nature including the major groups of plants and animals. Also, you will come to know about various health problems or diseases common in society and how they are caused. For instance, some diseases are caused by microbes, some are infectious while some are non-infectious. Then, you will be studying the concepts of organic farming, food production, and biochemical cycles in nature like the water cycle, oxygen cycle, nitrogen cycle and carbon cycle.
