If photosynthesis happens in plants, why is it considered a chemical reaction?

Question

Responses

because a chemical change happens where glucose and oxygen are rearranged into different molecules
because a chemical change happens where glucose and oxygen are rearranged into different molecules

because a physical change happens where the chemicals glucose and oxygen change state
because a physical change happens where the chemicals glucose and oxygen change state

because a physical change happens where the chemicals carbon dioxide and water change state
because a physical change happens where the chemicals carbon dioxide and water change state

because a chemical change happens where carbon dioxide and water are rearranged into different molecules

Answer 1

The correct response is:

because a chemical change happens where carbon dioxide and water are rearranged into different molecules.

Photosynthesis involves the transformation of carbon dioxide and water (along with sunlight energy) into glucose and oxygen, which is a process that changes the chemical composition of the starting materials, thus classifying it as a chemical reaction.
