Class 11 Biology Respiration In Plants Breathing of plants

Breathing of plants

  • Plants require O2 for respiration to occur which occurs through stomata and lenticels.
  • During the process of respiration, the complete combustion of glucose takes place, which produces CO2 and H2O as end products, yields energy most of which is given out as heat.

C6H1206 + 6O2 à 6CO2 + 6H20

  • All living organisms retain the enzymatic machinery to partially oxidise glucose without the help of oxygen, this breakdown of glucose to pyruvic acid is called glycolysis.
