What type of change occurs when glucose is formed from carbon dioxide and water during photosynthesis?
Answer and explanation
Correct answer: Chemical change
In photosynthesis, atoms from carbon dioxide and water are rearranged to form new substances such as glucose and oxygen. Since chemical bonds change and new substances are produced, it is a chemical change. It is not merely a change of state, because the substances do not just change their physical form; new substances are formed.
