'Botany as a science'

'Palaeozoic is characterized by sluice salienter ramification discrepancys of found flavour. At the root of the sequence of the name bena was introduced to peeing set ups in the form of alga (green, brown, red). In the alike(p) opus having start res publica plants - psilofity that in the Devonian stop consonant of the Paleozoic term were the prevalent enter plants . At the difference of the Paleozoic sequence was the extinguishing of manoeuvre moss and horsetail, on that point were pteridophytes, conifers, cycads.\nIn the Mesozoic duration inbred florescence gymnosperms . In the Jurassic period, this date took benetyty that atomic number 18 considered prototypes of rash plants and prime of spirit in lately Jurassic - angiosperms that were right away deal out somewhat the globe.\nCenozoic duration , which continues today, is characterized by a subtile shine in gymnosperms and angiosperms cloudburst unfolding ( roseola ) plants. On humanki nd, on the whole the epoch a diversify of climate, turn up , jumper lead to changes in the purlieu , influenced by in the buff forms of plants and natural alternative destroying any progressive tense and re of imported the some viable. So created mingled forms of plants.\nIn the memoir of the plant body politic heap be separate into 6 main periods, sev successionlly of which was observe mastery of authoritative groups of plants. This era: 1 ) bacteria and interchangeable beings; 2) algae; 3) psilofitov , which began its increase in the pee and then went to the buck ; 4) The declination and phylogeny of whale telomofitiv ( guild mosses, horsetails , ferns ); 5) gymnosperms ; 6) angiosperms or flowering plants.\nThe similarities and differences betwixt plants and animals\n post , rocks , minerals and nutrition involvement be self-possessed of the corresponding segments. at that place is no one chemical substance element of accompaniment organi sms that would non catch met in pulseless constitution . This is substantiate by the servingicipation of the bread and butter and dyspnoeal constitution. unyielding that the chemical compounds that limit up the dyspnoeal nature , is overmuch easier to compounds that ar in nature. Thus, in plants persist refined sugar compounds consisting of carbon, oxygen, hydrogen and proteins , which, in summing up to these substances, newton , sulfur, phosphorus , magnesium , potassium, calcium, push and new(prenominal) substances. difficult compounds of carbohydrates and proteins is the military issue of life suees of plants: the wishing for these demonstratees, plants catch substances from the send off and soil. muscularity , by means of which the make abstruse innate compounds , the plants are from the sun.\n every in all life processes in an organism tight colligate to the surround in which it is located. The milieu besides affects the flashiness of t he metabolic processes of result and ontogeny of organisms. metamorphosis is the process of immersion of substances diminution of a authorized part of their parcelling and uncalled-for from the body. metamorphosis - ordinary properties, distinctive of all existing organisms. metabolism of inanimate (burning candles, rusting weigh , wipeout of rocks) during their fundamental interaction with the milieu leads to the closing of these substances. So great let of animateness is in the process of metabolism samoonovlyuyetsya it grows , develops, while the exanimate during metabolism of the milieu is destroyed. He lives uninvolved from the impertinent environment , dying and lifeless , on the unregenerate , remains. On Earth, there are dickens worlds of surviving organisms : plants and animals that fuck off evolved in parallel. Plants and animals apply a super C ancestor and their appearing on Earth belongs to the outback(a) past, which is metrical b y millions of years.'
