breath - is a universal property of all living things that are on earth.The main property of the respiratory process is the absorption of oxygen interacting with living tissues by organic compounds to form water and carbon dioxide.Breath of plants is accompanied by the absorption of water plant organisms and in the surrounding area plants emit carbon dioxide.When breathing
for allocating power plant uses an organic substance, this process is the reverse of photosynthesis, when plant tissues accumulate nutrients.In the daytime, almost all plants produce oxygen, but the cells in their parallel holds the breathing process, but it occurs less rapidly.Night plant respiration activity occurs, unlike the photosynthesis, which avoid light, it stops.
Act respiration in plants
plant cells and, accordingly, all of the plant as a whole, there is provided a continuous supply of plastic materials and energy.The act of respiration, from a chemical point of view, is composed of many links in the chain associated redox reactions that occur between cell organelles and are accompanied by splitting substances.Excels at splitting energy is used to power the plant.
External plant respiration - a gas exchange between the body itself and the outside plant through the stomata or lenticels leaves in tree trunks.RESPIRATORY more highly organized plants are leaves, trunks, stems, each of the cells of algae.
tissue respiration
During cellular respiration in plants meet the special structure of the cells - the mitochondria.These organelles of plant cells differ greatly from those of animals that can be explained by the peculiarities of plant life (lifestyle - fixed, changes in metabolism due to the changeable environmental conditions).
Therefore respiration of plants is accompanied by additional pathways of oxidation of organic elements, which are produced by alternative enzymes.The algorithm can be represented schematically breath as the oxidation reaction of carbon dioxide and water to sugar, due to the absorption of oxygen.It is accompanied by heat, which is clearly apparent at blooming flowers and seed germination.Plant respiration - is not only the supply of energy for growth and further development of the plant.The role of breathing is very important.At the intermediate stage of the respiratory process generated organic compound is then used in the exchange of substances, for example, pentoses and organic acids.Breathing, photosynthesis and despite the fact that opposite in nature, are interconnected, as are the sources of energy carriers such as NADPH, ATP and metabolites in the cell.The water that is released during respiration, dry conditions persist in the plant from dehydration.Thus, if the process is too intense, excessive respiratory energy as heat can cause loss of dry matter of live cells.
