How does plants breathe

1.	How does plants breathe
Answer» Green plant respires all the time, day and night. All parts of the plant respire, the leaves, the stem, the roots and even the flowers. During the day, plants photosynthesize more than they respire so more carbon dioxide is used up than produced. A green plant photosynthesizes only in the presence of sunlight. While the sun shines, plants perform photosynthesis. In this process, the plants convert sunlight, water and carbon dioxide into stored energy in the form of long chains of sugar, called starch. At night, plants do the respiration and gets energy. In this process the plants burn this stored starch to fuel for continue the growth.The breakdown of this fuel takes place in the cytoplasm and in the mitochondria. The breaking of the C-C bonds of complex compounds through oxidation within the cells, leading to release of considerable amount of energy is called respiration. This energy trapped as chemical energy in the form of ATP. The complete combustion of glucose produces CO2 and H2O as end products along with heart energy.
