Gaseous Exchange in Plants | Chapter 9 | Lecture 6 | Class 9 biology new book

Welcome to science with Rumaisa! In this video, we will explain Gaseous Exchange in Plants in a simple and clear way. You’ll learn how plants exchange oxygen and carbon dioxide during photosynthesis and respiration and how structures like stomata and lenticels help in this process. We cover: ✅ Gaseous exchange during day and night ✅ Role of stomata and lenticels ✅ Gaseous Exchange in Plants ✅ Gaseous Exchange in Woody Stems ✅ Process of Gaseous Exchange in Plants This topic is a part of Chapter 9: Plant Physiology from the Class 9 Biology syllabus, and is helpful for exam preparation and concept building, and (Matric) level studying under Federal Board, Punjab Board, Sindh Board, and other boards in Pakistan and India.
