how are photosynthesis and cellular respiration alike and different kids answer
Cellular respiration takes a glucose molecule and combines it with oxygen; the result is energy in the form of ATP, along with carbon dioxide and water as waste products. Photosynthesis takes carbon dioxide and combines it with water, enabled by radiant energy, usually from the sun. The end result is glucose, with oxygen being the waste product. The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that photosynthesis assembles the glucose molecule, while cellular respiration takes it apart. The win-win of the two processes is that they both provide each other with the necessary ingredients for the process to take place: glucose and oxygen for cellular respiration, carbon dioxide and water for photosynthesis.
