This 46 slide PowerPoint presentation includes information regarding Photosynthesis. This PowerPoint includes easy-to-follow, but detailed descriptions of the structure of chloroplasts, the light dependent reactions, the light independent reactions also called the Calvin Cycle and carbon fixation. This PowerPoint also includes many diagrams and pictures to help ensure student understanding. I have used this PowerPoint with my grade 11/12 Biology class. This is a lengthy PowerPoint, with awesome information. I usually deliver this PowerPoint in at least two lessons. Feel free to download and edit this PowerPoint. Please do whatever works best for you!
