Here's how: Just in case you missed it, the ID number for the Photosynthesis and Cell Respiration project in WISE is 9932. There are a few illustrations and clear descriptions of each stage of the main reactions. electron transport chains, hydrogen gradients, and splitting water molecules. Once we conclude, I tell the students that we will continue our study of this process through a series of interactives and visualizations on a site called WISE. Before attempting to access the interactive with the students, the teacher must have created an account, and started a run of the "Photosynthesis and Cell Respiration" project. Photosynthesis cannot occur without cellular respiration and cellular respiration certainly cannot occur without the photosynthesis. Compare the leaves of a plant that has all the components needed for photosynthesis to one that has a component missing → Chlorophyll, sunlight, CO 2 and water are essential raw materials for photosynthesis.
