Class 9 ICSE Biology

The notification for the board exams is already out and preparations for the Science subject consume a major portion of your time. But having a strategic study plan makes it easy to prepare for it. The Indian School Certificate Examinations (CISCE) conducts  ICSE for class 10th. A minimum of 33% marks are required to qualify for the exam but preparing beforehand can help you score well. In this blog, we will have a look at the Class 9 ICSE Biology syllabus.

Class 9 ICSE Biology: Exam Pattern

Before beginning your preparations, understanding the paper pattern is essential. Doing so would not only help you make an efficient study plan but also give you an idea of how much time to give on each topic. The 9 ICSE Biology paper will be divided into two sections and each section carrying 40 marks forming a total of 80 marks. The Internal Assessment of Practical work carries 20 marks. Section-I has Short Answer-type Questions and all of them are compulsory, while Section-II contains six questions out of which only four are to be answered. 

Class 9 ICSE Biology Syllabus

Consisting of 7 chapters, the coursework has been designed to solidify the understanding of the subject which forms the base for medical courses to be taken after the 12th class. Given below is the chapter-wise syllabus for Class 9 ICSE Biology.

Class 9 ICSE Biology Syllabus: Internal Assessment

Now let us take a look at what all is under the syllabus of the Internal Assessment of Biology for class 9-

Plant Life 

  • The examination of an onion peel under the microscope to study various parts of the cell. 
  • A cross-pollinated flower to be examined and identified and the parts to be studied and labelled e.g. Hibiscus.
  • Specimens of germinating seeds with plumule and radicle (the bean seed and maize grain) for examination, identification, drawing and labelling the parts.

Animal Life

  • The examination of a human cheek cell under the microscope to study various parts of the cell.
  • Identification of sugar, starch, protein, and fat. through the conduct of relevant tests.
  • Examination and identification of specimens belonging to the following groups of animals: Non-Chordata – Porifera, Coelenterata, Platyhelminthes, Nemathelminthes Annelida, Arthropoda. Mollusca and Echinodermata. Chordata- Pisces, Amphibia, Reptilia, Aves, Mammalia. Identification of the structure of the following organs through specimens/models and charts: Lung and skin.
  • Experiments to show the mechanism of breathing. Bell jar experiment should be discussed. The comparison should be made with the human lungs and respiratory tract to show the mechanism of breathing.
  • Visit a few establishments in the locality such as motor repair workshops, kilns, pottery making units, fish and vegetable markets, restaurants, dyeing units. Find out the types of wastes and methods prevalent for their disposal. On the basis of the information collected, prepare a report, suggest measures to improve the environmental conditions.
  • Visit a water treatment plant, sewage treatment plant, or garbage dumping or vermicomposting sites in the locality and study their working
