Final answer:
Water produces electrons and hydrogen ions during light-dependent reactions, carbon dioxide is used to produce sugars during light-independent reactions, and sugars are one of the main outputs of photosynthesis.
Step-by-step explanation:
The inputs and outputs of photosynthesis are:
- The role of water molecules is to produce electrons and hydrogen ions during the light-dependent reactions.
- Carbon dioxide is the matter for sugars during the light-independent reactions.
- One of the main outputs of photosynthesis is sugars.
