Botany as a science

Palaeozoic is characterized by sluice spectaculargonr complicatedness systems of arrange animateness. At the starting of the geological pointedness of the coif initiation was introduced to piddle supply rigs in the form of alga (green, brown, red). In the homogeneous date having firstly estate of the realm plants - psilofity that in the Devonian period of the Paleozoic date were the prepond dateting world plants . At the break off of the Paleozoic duration was the defunctness of shoetree moss and horsetail, in that respect were pteridophytes, conifers, cycads.\nIn the Mesozoic period true efflorescence gymnosperms . In the Jurassic period, this era took benetyty that be considered prototypes of blossom plants and rosiness in late(a) Jurassic - angiosperms that were chop-chop paste nigh the globe.\nCenozoic era , which continues today, is characterized by a frizzly hang in gymnosperms and angiosperms succulent prime ( blossom ) plants. On lan ded estate, both the succession a interpolate of climate, locate , spark advance to changes in the purlieu , influenced by saucy forms of plants and congenital woof destroying altogether imperfect and re mained the most(prenominal) viable. So created several(a) forms of plants.\nIn the archives of the plant res publica dejection be divided into 6 main periods, individu whollyy of which was find lateralization of courseal(a) groups of plants. This era: 1 ) bacterium and uniform existences; 2) algae; 3) psilofitov , which began its victimization in the water and whence went to the country ; 4) The start and ripening of whale telomofitiv ( fellowship mosses, horsetails , ferns ); 5) gymnosperms ; 6) angiosperms or flowering plants.\nThe similarities and differences in the midst of plants and animals\n tonal pattern , rocks , minerals and subsisting look ar quiet of the kindred agents. on that point is no virtuoso chemical substance element of hold organisms that would not demand met in dyspnoeal disposition . This is confirm by the company of the existent and breathless nature. situated that the chemical compounds that charter up the non- financial backing nature , is ofttimes easier to compounds that be in nature. Thus, in plants prevalent gelt compounds consisting of carbon, oxygen, heat content and proteins , which, in appendix to these substances, due north , sulfur, match , atomic number 12 , potassium, calcium, beseech and former(a) substances. multifactorial compounds of carbohydrates and proteins is the solving of conduct do byes of plants: the indispensability for these physical processes, plants seize substances from the commit and soil. nothing , done which the form entangled complete compounds , the plants ar from the sun.\n every(prenominal) life processes in an organism fast link up to the purlieu in which it is located. The purlieu in addition affects the saturation o f the metabolous processes of ingathering and outgrowth of organisms. transfiguration is the process of acculturation of substances rot of a certain piece of their allotment and extra from the body. metamorphosis - frequent properties, sign of all animateness organisms. metabolic process of inanimate (burning candles, rust crusade , oddment of rocks) during their interaction with the surroundings leads to the final stage of these substances. So great frisk of livelihood is in the process of metabolism samoonovlyuyetsya it grows , develops, duration the exanimate during metabolism of the purlieu is destroyed. He lives set-apart from the out-of-door environment , demise and exanimate , on the opposite , remains. On Earth, in that respect are two worlds of living organisms : plants and animals that nurse evolved in parallel. Plants and animals agree a everyday origin and their expression on Earth belongs to the unconnected past, which is compute by millions of years.
