To indicate the activity of photosynthesis in a plant, it was plunged in water and observed as bubbles of gas floated to the surface over time.
Was the gas:
A) oxygen
B) carbon dioxide

Respuesta :

C) Both.
Plants go through photosynthesis (producing Oxygen), but to consume the sugars they have created they have to go through cellular respiration as well, which produces carbon dioxide. All organisms go through cellular respiration.
