CBSE Respiration in Plants Class 11 MCQs of Biology Chapter 12

Respiration in Plants MCQs: The CBSE Class 11 paper pattern is the same as that of CBSE Class 12 because the Class 11 standard is considered the preparatory phase for students to get ready for the CBSE Class 12 board exams. As per the CBSE paper pattern, the first section of the CBSE Class 11 Biology paper would be of one-mark questions, which majorly include MCQs along with assertion and reason-based questions. Thus, having proper command over MCQs is important to score well in the final exams. The best way to do that is to practice MCQs regularly.

To help you prepare better, our experts have created Respiration in Plants Class 11 MCQs with answers. Go through these MCQs to understand the Chapter, Respiration in Plants, of Class 11 Biology. Also, these Respiration in Plants class 11 MCQ questions will help you understand the different ways in which a question can be asked during your final exam.
