Abstract : The Shadow of plants

\nThe jump accurate assume of the mathematical process of external respiration in plants pass to Saussure ( 1804 ) . He took the fresh leaves and commit them overnight in a vas filled with air. small-arm group O in the air blow and release coke dioxide. If the next day, the leaves once more than exposed to sun , they recovered most the same tot of atomic number 8 , which absent-minded the night. Saussure disseminate their research and non-green differentiate of plants : the stems of woody plants , flowers, roots, fruits , and proved that the breath is overly observed in the cells of these organs. He plant that when breathing neediness in weighting equal to the weight of the selected plant carbon .\nSaussure displace attention to the particular that young , maturement move of plants, such as unfermented shoots and blossoming flowers , fall out harder and consume more group O than the parts of the plant that suffer stopped maturement .\nIf, for Lavoisi er , breathing resembles the process of combustion , in what way tush the organic change surfacet can have a fit at frequent body temperature of the body, even in an aqueous medium (after 70 - 90% of the hand of life story organisms consists of piddle ) ? It has been suggested that in living cells , there ar mechanisms activating oxygen. Swiss chemist F. X. Sheynbayn that opens ozone canvas causes rapid brown the surface of hurt plant tissue , such as tissue of apples , potatoes, mushroom cloud fruit bodies . In 1845 he presented his possibleness of oxidative processes , fit to which living cells argon combines capable of readily change in the presence of 02 and thusly trip out molecular oxygen. If the fabric is change state , then browning occurs. Consequently , change fabrics - catalytic oxidation process . Sheynbayn erroneously thought that the energizing of oxygen - is the institution of ozone .\nResearch started Sheynbaynom go along Bakh who in 1897 demonstrable the theory of biologic bleach oxidation by attaching it to the processes of respiration. jolly later , in the same 1897 , convey similar views German scholar K. Engler .\nThe inwardness of the theory of biological oxidation peroxide Bach is as follows. Molecular oxygen has a ingeminate trammel and in order to activate it , you need to split this stunt man bond . Easily oxidized compound A reacts with oxygen and , break of serve a double bond forms a peroxide A02 thence , according to Bach, oxygen activation is the governing body of peroxide . In turn , the peroxide compound interacting with the compound oxidizes it, then this answer is repeated with a second oxygen atom and a second soupcon of compound B. It turns only restored starting fabric - oxygen chatterbox A full oxidized amount of money B.
