Question

Which number remains unchanged during photosynthesis? (1 point)
• the number of carbon atoms
•
• the number of glucose molecules
•
the number of carbon dioxide molecules
• the number of water molecules

Answer 1

During photosynthesis, the number of carbon atoms remains unchanged in terms of the balance between reactants and products. Photosynthesis converts carbon dioxide and water into glucose and oxygen, but the total number of carbon atoms in the system remains the same.

So, the correct answer is:
- the number of carbon atoms.
