Why is photosynthesis an example of a chemical reaction, and why is it classified as endothermic?

Help please

nvm I got my answer :)
photosynthesis is a chemical reaction through which plant converted solar energy in to chemical energy, this chemical energy is stored in the form of carbohydrate (glucose) which is necssory for plant activities such as growth, maintains, survival etc

the Rxn is
6CO2+6H2O ......C6H12O6+ 6H2O

light is used as a energy during this reaction so for its endothermic
It's Endothermic because energy in form of light is being given off
It's Endothermic because energy from the sun is transmitted as energy
Yep...I'm watching this one too...always watching. You can go ahead and copy it if you like. I love the extra paperwork and parent phone calls. NOT!
Creepy.
How can you say that when you posted a question on this very website?!
Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun’s electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant. Sunlight is the primary source of energy on the surface of Earth.
