Final answer:
During photosynthesis, matter is transformed from carbon dioxide and water into glucose and oxygen, following the Law of Conservation of Mass which retains the same overall mass.
Step-by-step explanation:
The question is centered around what happens to the matter used during photosynthesis. To address this question, we refer to the Law of Conservation of Mass, which states that matter cannot be created or destroyed, only transformed. During photosynthesis, carbon dioxide (CO2) from the atmosphere is used along with water (H2O) to produce glucose (C6H12O6) and oxygen (O2). This process transforms the matter from one form to another but does not change the overall mass. Hence, the answer to the question is: d) It changes to a new form of matter with the same mass.
The Calvin cycle, which is part of photosynthesis, involves the incorporation of carbon from CO2 into organic molecules. This cycle results in the production of glucose, which is a sugar that plants use for energy and growth, while also regenerating the initial molecules needed to continue the cycle.
