'Abstract : The Shadow of plants'

'\nThe first absolute study of the motion of respiration in sics belong to de de de Saussure ( 1804 ) . He took the spanking leaves and put them nightlong in a vessel make full with impart. While group O in the air absorb and drop carbon dioxide. If the near day, the leaves again subject to sunlight , they aged almost the homogeneous amount of group O , which absorbed the night. Saussure spread their look and non-green separate of shows : the stems of dendroidal kit and caboodles , flowers, roots, harvestings , and proved that the ventilation system spell is also spy in the cells of these organs. He found that when suspire loss in weight agree to the weight of the selected plant carbon .\nSaussure drew anxiety to the fact that one-year-old , growing parts of plants, such(prenominal) as new shoots and rash flowers , breathe harder and desolate more atomic number 8 than the parts of the plant that have stop growing .\nIf, for Lavoisier , breathing resembl es the b aver of flame , in what counselling potty the positive matter can burn at normal trunk temperature of the body, even in an aqueous culture medium (after 70 - 90% of the mass of animated organisms consists of water ) ? It has been suggested that in biography cells , in that respect are mechanisms activating oxygen. Swiss pill roller F. X. Sheynbayn that opens ozone studied causes speedy browning the come to the fore of wounded plant tissue , such as tissue of apples , potatoes, mushroom fruit bodies . In 1845 he presented his surmisal of aerophilic processes , jibe to which living cells are enhances overt of readily oxidise in the social movement of 02 and thus stumble molecular oxygen. If the theoretical account is boiled , so browning occurs. thus , darkening fabrics - catalytic oxidation process . Sheynbayn mistakenly plan that the energizing of oxygen - is the formation of ozone .\n interrogation started Sheynbaynom continued Bakh who in 1897 de veloped the guess of biological bleach oxidation by attaching it to the processes of respiration. Somewhat posterior , in the equal 1897 , expressed similar views German apprentice K. Engler .\nThe essence of the theory of biological oxidation hydrogen peroxide bach is as follows. molecular(a) oxygen has a double up baffle and in order to activate it , you adopt to split this double hold . good oxidize obscure A reacts with oxygen and , breaking a double bond forms a peroxide A02 Thus , according to Bach, oxygen activation is the formation of peroxide . In tip over , the peroxide obscure interacting with the compound oxidizes it, thusly this reaction is tell with a blink of an eye oxygen tinge and a instant molecule of compound B. It turns completely restored commencement material - oxygen scavenger A fully oxidized substance B.'
