Can someone tell me about cellular respiration and photosynthesis?

Can someone tell me the differences between respiration and photosynthesis?

• Questions: which requires molecules of carbon dioxide to start? ~ requires glucose/organic molecules to start? ~ molecules of Oxygen to complete? ~ molecules of Water to start? ~ light energy to start? ~ produces glucose molecules? ~ produces oxygen molecules? ~ produces ATP from food energy? ~ do humans and animals use this? ~ decomposers and detritus feeder do this? ~ algea and other green plants do this? All these question are from my homework. Which of the two (cellular respiration and photosynthesis) answers each question? Please help!!!

• Answer:

  Photosynthesis is the process that all green plants use to convert water and nutrients with the aid of chlorophyll and energy from sunlight into food(glucose). respiration is only part of the process that allows all living things(including plants) to produce energy via andosine triphosphate breakdown to grow, move and reproduce. respiration is the process of transporting air(oxygen)into the body to allow breakdown of food into energy and waste products girl, you need more confidence in yourself. i don't have a major in biology, infact i only have what you call high school education. some people may want to fool you. God bless, gabe ps, algae is a plant, it may be single celled , but still a plant.
