Will give brainlist, points, stars, etc. can someone me reword this ? i don't like how i did it. photosynthesis turns carbon dioxide and water into oxygen and carbohydrates, therefore a chemical change happens. it is also an endothermic reaction because energy needs to be inputted in order for photosynthesis to occur. the energy input is then stored in the bonds of the glucose that were formed as a result of photosynthesis.

Photosynthesis turns sunlight, water and carbon dioxide into energy and oxygen. Clorophyll is also a result of this process. "Photosynthesis turns carbon dioxide and water into oxygen and carbohydrates, therefore a chemical change happens." (keep what you wrote there) "It is also an endothermic reaction because SOLAR energy needs to be inputted in order for photosynthesis to occur. The energy input is then stored in the bonds of the glucose that were formed in the plant as a result of photosynthesis."
