The starting ingredients for photosynthesis are water, oxygen and sunlight. Photosynthesis is the process by which plants make their food. During this process, plants take in carbon dioxide and breathe out oxygen and thus they try to balance the nature. We the animals breathe in oxygen and breathe out carbon dioxide and so a mutually beneficial circle continues. After photosynthesis the glucose is distributed to every part of the plant with the help of Phloem. This process is important to continue the cycle of life.
they are carbon dioxide, water and sunlight. Sunlight acts as the catalyst. photosynthesis is the build up of larger food molecules by plants from smaller molecules to give glucose and oxygen. 6CO2 + 6H2O = C6H12O6 + 6O2
