Which of these are waste products of photosynthesis?

Oxygen
Water
Carbon dioxide
ATP

Oxygen

Explanation:

The photosynthesis equation is:

water (H2O) + carbon dioxide (CO2) + sunlight ---> glucose (C6H12O6) + oxygen (02)

The plant uses the glucose as food and to fuel all the plant's cellular activities. The plant does not use oxygen, therefore it is a waste product.

Hope this helps! :)
