NCERT Class 11 Biology Chapter 14 Breathing and Exchange of Gases Test Mock Test

This free online test covers Chapter 14, Breathing and Exchange of Gases, from the NCERT Class 11 Biology textbook. The 30 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.
