Photosynthesis is considered a chemical change. Why?
Because it involves the transport of water from root to leaf
Because it is a complicated processed involving plant organelles
Because the elements in H20 and C02 break their bonds and rearrange to form glucose and oxygen
Because oxygen and carbon dioxide enter and exit the plant but remain unchanged during the cycle
