Question

Photosynthesis in an aquatic plant was measured by counting the number of $O_{2}$ bubbles coming out of the cut end of the plant. What will happen to $O_{2}$ production if you use a pipe blow air from your mouth into water in the beaker?

Air from mouth contains $O_{2}$ which is being added to the plant. Hence increase in $O_{2}$ production.

Plants use CO₂ for photosynthesis during the day . But at night , they also respire ,i.e.,take in O₂ and release CO₂ into the air . This doesn't help much in the reduction of CO₂ . Then why do people ask to plant more trees ? Is there a more effective method to reduce CO₂ in the air ?
