What is the purpose of photosynthesis in plants?
Photosynthesis in plants is for water absorption and carbon dioxide release.
The purpose of photosynthesis in plants is to produce food (glucose) and oxygen.
The purpose of photosynthesis in plants is to produce heat and light.
Photosynthesis in plants is to convert oxygen into carbon dioxide.
How does photosynthesis contribute to the oxygen cycle?
Photosynthesis contributes to the oxygen cycle by releasing carbon dioxide into the atmosphere.
Photosynthesis contributes to the oxygen cycle by reducing the amount of oxygen in the atmosphere.
Photosynthesis contributes to the oxygen cycle by releasing oxygen into the atmosphere.
Photosynthesis contributes to the oxygen cycle by absorbing oxygen from the atmosphere.
