Respiration – The process of metabolizing (burning) sugars to yield energy for growth, reproduction, and other life processes.

In respiration, plants (and animals) convert the sugars (photosynthates) back into energy for growth and other life processes (metabolic processes).  The chemical equation for respiration shows that the photosynthates are combined with oxygen releasing energy, carbon dioxide, and water.  A simple chemical equation for respiration is given below.  Notice that the equation for respiration is the opposite of that for photosynthesis.

Chemically speaking, the process is similar to the oxidation that occurs as wood is burned, producing heat.  When compounds combine with oxygen, the process is often referred to as “burning”, for example, athlete’s “burn” energy (sugars) as they exercise.  The harder they exercise, the more sugars they burn so the more oxygen they need.  That is why at full speed, they are breathing very fast.  Athletes take up oxygen through their lungs.  Plants take up oxygen through the stomata in their leaves and through their roots.

Again, respiration is the burning of photosynthates for energy to grow and to do the internal “work” of living. It is very important to understand that both plants and animals (including microorganisms) need oxygen for respiration. This is why overly wet or saturated soils are detrimental to root growth and function, as well as the decomposition processes carried out by microorganisms in the soil.

The same principles regarding limiting factors are valid for both photosynthesis and respiration.
