Question

Photosynthesis in an aquatic plant was measured by counting the number of O2 bubbles coming out ofthe cut end ofthe plant. What will happen to O2 production if you use a pipe to blow air from your mouth into water in the beaker?

  1. Air from mouth contains O2 which is being added to the plant. Hence increase in O2 production
  2. Air from mouth contains CO2 which is utilized in photosynthesis. Hence increase in O2 production
  3. Bacteria from mouth will infect plant. Hence reduction in O2 production
  4. Water is already in contact with air. Hence air from mouth will have no effect

A
Air from mouth contains O2 which is being added to the plant. Hence increase in O2 production
B
Bacteria from mouth will infect plant. Hence reduction in O2 production
C
Water is already in contact with air. Hence air from mouth will have no effect
D
Air from mouth contains CO2 which is utilized in photosynthesis. Hence increase in O2 production
Solution
Verified by Toppr

The correct option is B Air from mouth contains CO2 which is utilized in photosynthesis. Hence increase in O2 production
Photosynthesis is the process in which green plants use the sunlight to convert carbon dioxide, water and minerals to oxygen and organic compounds. In the given experiment, when a pipe is used to blow air from mouth in the beaker, the air from mouth is utilized in photosynthesis, as human beings breathe out carbon dioxide. It results in the increased production of oxygen.

Plants use CO​​2 for photosynthesis during the day . But at night , they also respire ,i.e.,take in O​​​​​​2 and release CO2​​​​ into the air . This doesn't help much in the reduction of CO​​​​​2 . Then why do people ask to plant more trees ? Is there a more effective method to reduce CO​​​​​2 in the air ?
