Question

based on what you have observed in the gizmo, which of the following chemical equations represents photosynthesis?
carbon dioxide plus water yields glucose (sugar) and oxygen
water plus glucose yields oxygen and carbon dioxide
oxygen plus carbon dioxide yields water and glucose
glucose plus oxygen yields carbon dioxide and water

Explanation:

Photosynthesis is a process where plants use carbon dioxide (\(CO_2\)) and water (\(H_2O\)) in the presence of sunlight to produce glucose (\(C_6H_{12}O_6\)) and oxygen (\(O_2\)). Option a correctly represents the reactants (carbon dioxide and water) and products (glucose and oxygen) of photosynthesis. Option b has glucose as a reactant which is incorrect as glucose is a product. Option c has oxygen as a reactant which is wrong (oxygen is a product). Option d has glucose as a reactant (again, glucose is a product in photosynthesis).

Answer:

A. Carbon dioxide plus water yields glucose (sugar) and oxygen
