CBSE Class 9 Biology Mid-Term 2026: Important Questions & Concepts to Prepare From PW Marathon

Biology revision for the Class 9 Mid-Term exam can be challenging when you have to remember cell organelles, tissue types, their functions and important diagrams. Questions may also test whether you can identify a tissue, understand its function or recall where it is found.

The PW  CBSE Class 9 Biology Marathon helps you revise important Biology concepts in detail and practise questions based on topics covered for the exam. From cell structure and organelles to plant and animal tissues, the marathon focuses on difficult concepts, important questions and areas that need extra revision.

How Can the PW Class 9 Biology Mid-Term Marathon Help With Revision?

The PW Class 9 Biology Mid-Term Marathon is planned for detailed revision of important chapters and difficult areas that students often struggle with before the Mid-Term exam. You can expect:

• Detailed Chapter Revision: Revise the important Biology chapters covered in the Half-Yearly syllabus in detail instead of only getting a quick overview.

• Cell and Cell Organelle Revision: Strengthen concepts related to cells, cell organelles and their functions, including the rough endoplasmic reticulum and ribosomes.

• Cell Diagram Practice: Revise important cell diagrams and clear common difficulties related to identifying and understanding cell structures.

• Plant Tissue Concepts: Revise meristematic tissues, their types and functions, with special focus on apical, lateral and intercalary meristems.

• Intercalary Meristem in Detail: Understand how intercalary meristem helps increase stem height and supports regeneration after grazing.

• Animal Tissue Revision: Revise epithelial and muscular tissues, including their locations, functions and identifying features.

• Important Question Practice: Solve questions during the revision to check your understanding of the concepts being discussed.

• Concepts Explained From the Basics: Difficult Biology topics are explained step by step so you can understand the concept before attempting related questions.

• Exam-Focused Revision: Focus on concepts, diagrams and questions that can help you revise important Biology areas before the Mid-Term exam.

• Extended Revision Session: The marathon allows enough time for detailed topic coverage and question practice rather than rushing through the syllabus.

Strong Biology preparation requires more than memorising answers. Revise the concepts behind each question, understand the functions and characteristics of cells and tissues, and practise important questions regularly. Use the PW Class 9 Biology Marathon along with these questions to strengthen your revision and approach the Mid-Term exam with greater confidence.
