Photosynthesis Concepts and Processes

The video tutorial provides a comprehensive overview of photosynthesis, explaining how plants convert sunlight into chemical energy to produce glucose and oxygen. It covers the photosynthesis equation, the role of chloroplasts, and the two main reactions: the light-dependent reaction and the Calvin cycle. Key vocabulary and concepts are recapped to reinforce understanding.
