Plants have small , minute pores on the lower surface of their leaves known as stomata , which help in the exchange of gases and they have certain semi-permeable membranes which allows only the desired gases to enter (CO_{2} andO  _{2} ) and blocks the entry of other substances. The reactions are Given below....
Respiration:
C_{6} H _{12} O _{6} +6O _{2} =6CO _{2} +6H _{2} O+38 ATP + 420 Kcal.
Energy is released in the form of Adenosine Triphosphate (ATP) and Heat is released in Kilocalories.
Photosynthesis:
6CO _{2} +6H _{2} O=C_{6} H _{12} O _{6} +6O _{2}  
Glucose is the food whereas oxygen is a by-product.
