__ Photosynthesis and Cellular Respiration __
check out this canvas for information and inspiration media type="custom" key="22389140" Watch a video on photosynthesis. The following videos help bring photosynthesis to life. National Geographic Video  How Stuff Works Video Play the Photosynthesis Games  Photosynthesis Formula Game   Photosynthesis Jeopardy
 * 1) Create a poster, booklet, powerpoint, glog, educanvas or presentation comparing and contrasting photosynthesis and cellular respiration. Include:
 * 2) Location of each process (*NOTE: In plant cells both photosynthesis and cellular respiration occur. In animal cells, only cellular respiration occurs)
 * 3) A labeled diagram of each cycle’s: Reactants, Products, Energy flow
 * 4) Explain how photosynthesis and cellular respiration differ in terms of energy flow, reactants and products.
 * 5) Identify similarities between the cycles
 * 6) Explain how photosynthesis and cellular respiration depend on each other.
 * Discuss with the teacher: **
 * 1. Explain how photosynthesis and cellular respiration differ in terms of energy flow, reactants, and products.**
 * 2. Could photosynthesis exist without cellular respiration? Could cellular respiration exist without photosynthesis? Defend your position.**
