ICSE Biology Syllabus for Class 9: When we hear the term Biology all that comes to mind are plants and animals, living beings in short. Yes, it is a very normal reaction of the brain to stimuli based on certain pre-invested memories or learnings. There are organisms when cut into pieces regenerate a complete body from each. Sounds interesting! Such things fascinate students to take biology as one of their electives. The subject is diverse and the most amazing part, it has no long calculations to tackle. Well, it is a good part for many. At the level of class 9, biology as a subject introduces students to many new topics, terms and concepts. To highlight all those in more detail we are going to provide the well-framed, CISCE-approved syllabus for ICSE Class 9 Biology syllabus 2024.  Let us start with a quick revision of the aims set by CISCE for the 2023-24 Biology syllabus. 

2023-24 ICSE Class 9 Biology Syllabus Aims;

  1. To acquire knowledge of the economic importance of plants and animals. 
  2. To understand the interrelationship between sustainability and environmental adaptations. 
  3. To develop an understanding of the interdependence of plants and animals so as to enable pupils to acquire a more precise comprehension 
  4. of the significance of life and its importance in human welfare. 
  5. To understand the capacities and limitations of all the biological and economic activities so as to be able to use them for a better quality of life. 
  6. To acquire the ability to observe, experiment, hypothesize, infer, handle equipment accurately and make correct recordings.

Now that we know the multiple aims of the Biology ICSE Class 9 syllabus 2023-24, it is time to start with the general guidelines we must be aware of. 

ICSE Class 9 Biology Syllabus General Guideline:

  • There will be one paper of two hours duration of 80 marks and an Internal Assessment of practical work carrying 20 marks. 
  • The paper will be divided into two sections, Section I (40 marks) and Section II (40 marks). 
  • Section I (compulsory) will contain short answer questions on the entire syllabus. Section II will have six questions. Candidates will be required to answer any four of these six questions.
