Gas Exchange in Flowering Plants - GCSE Biology (9-1)

This video is for Edexcel IGCSE Biology 9-1 but is relevant for many GCSE Biology courses. It covers these specific objectives from the syllabus

2.40B Understand the role of diffusion in gas exchange.
2.41B Understand gas exchange (of carbon dioxide and oxygen) in relation to respiration and photosynthesis.
2.42B Understand how the structure of the leaf is adapted for gas exchange 2.43B Describe the role of stomata in gas exchange.
2.44B Understand how respiration continues during the day and night, but that the net exchange of carbon dioxide and oxygen depends on the intensity of light.
2.45B Practical: investigate the effect of light on net gas exchange from a leaf, using hydrogen-carbonate indicator.
