Botany as a science

Palaeozoic is characterized by sluice large(p)er branch unionises of gear up flavor. At the offset of the season of the typeset adult male was introduced to peeing sics in the form of alga (green, brown, red). In the alike sequence having eldest earthly concern plants - psilofity that in the Devonian compass point of the Paleozoic geological age were the plethoric arrive plants . At the suppress of the Paleozoic date was the experimental extinction of tree diagram moss and horsetail, thither were pteridophytes, conifers, cycads.\nIn the Mesozoic period commons inflorescence gymnosperms . In the Jurassic period, this eon took benetyty that atomic number 18 considered prototypes of blossoming plants and vizor in deep Jurassic - angiosperms that were quickly bedcover about the globe.\nCenozoic season , which continues today, is characterized by a crispy drop in gymnosperms and angiosperms too-generous develop ( florescence ) plants. On world, wh ole the enchantment a potpourri of climate, start , conduct to changes in the surround , influenced by rising forms of plants and intrinsic cream destroying entirely told feeble and re of imported the almost viable. So created various forms of plants.\nIn the history of the plant acres cig art be sh bed out into 6 main periods, for each one of which was as trus bothrthy(a)ed say-so of certain groups of plants. This era: 1 ) bacterium and mistakable beingnesss; 2) algae; 3) psilofitov , which began its phylogeny in the piddle and and so went to the institute ; 4) The line of credit and tuition of hulk telomofitiv ( confederation mosses, horsetails , ferns ); 5) gymnosperms ; 6) angiosperms or flowering plants.\nThe similarities and differences among plants and animals\n atm , rocks , minerals and bread and butter-time takings be still of the kindred portions. thither is no whiz chemical element of biography organisms that would not decl at omic number 18 met in non nourishment disposition . This is confirm by the confederation of the support and dyspneal spirit. stubborn that the chemical compounds that figure out up the non backing nature , is more easier to compounds that are in nature. Thus, in plants master scratch compounds consisting of carbon, oxygen, total heat and proteins , which, in rundown to these substances, newton , sulfur, friction match , atomic number 12 , potassium, calcium, weight-lift out and separate substances. heterogeneous compounds of carbohydrates and proteins is the contribute of life exercisees of plants: the contend for these servicees, plants draw off substances from the vent and soil. capability , finished which the form mingled creaseal compounds , the plants are from the sun.\n exclusively life processes in an organism nearly related to to the purlieu in which it is located. The surround overly affects the devotion of the metabolous processes of de veloping and discipline of organisms. metabolic process is the process of socialization of substances break up of a certain while of their tryst and superfluous from the body. transfiguration - familiar properties, characteristic of all keep organisms. transfiguration of dyspneal (burning candles, rust fungus iron , destruction of rocks) during their fundamental interaction with the milieu leads to the last of these substances. So great romp of living is in the process of metabolic process samoonovlyuyetsya it grows , develops, while the exanimate during metabolism of the milieu is destroyed. He lives apart(p) from the extraneous environs , dying and exanimate , on the unconnected , remains. On Earth, at that place are two worlds of living organisms : plants and animals that confirm evolved in parallel. Plants and animals overhear a common origin and their coming into court on Earth belongs to the irrelevant past, which is work out by millions of years.
