I believe they get their from the Sun to start the reaction :)
oxygen
Sunlight
cuz the sun gives energy to everything like plants and photosynthesis
every thing come from the sun the plants get there energy from the sun so that's where the source
By definition, all plants have to use photosynthesis. This begins once light reaches the plant.
The sunlight is used to process photosynthesis. hi ppl
Plant food starts out as glucose, which is a type of simple sugar. Glucose is produced during photosynthesis and serves as an important energy source for plants.
The energy needed to start a chemical reaction is called the activation energy :)
The energy needed to statr a chemical reaction is the 'Activation Energy' , which is given the symbol (Ea).
The reactants of photosynthesis are carbon dioxide, water, and the presence of light energy. The products are glucose or C6H12O6 and oxygen.
Its creates starch. Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. the reaction from start to finish is; 6CO2 + 6H2O (+ light energy) C6H12O6 + 6O2.This reaction is also responsible for the production of our oxygen.
