Liver is one of the most important organs of the gastrointestinal system. This organ is responsible for helping the digestive system digest food, detoxify the body and breakdown harmful substances that may be present in the body.

Photosynthesis is how a plant get its energy, cellular respiration converts energy into ATP then it releases waste. Kinda like letting the plants breathe. They are related because Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
