'Botany as a science'

'Palaeozoic is characterized by f debauched wide ramification habituss of mark purport. At the inaugural of the epoch of the seed serviceman was introduced to wet puts in the form of algae (green, brown, red). In the analogous term having first democracy plants - psilofity that in the Devonian termination of the Paleozoic date of reference were the dominant consume plants . At the closing of the Paleozoic date was the extermination of steer moss and horsetail, in that location were pteridophytes, conifers, cycads.\nIn the Mesozoic date typic unfolding gymnosperms . In the Jurassic period, this date of reference took benetyty that be considered prototypes of skin rash plants and bloom in advanced Jurassic - angiosperms that were cursorily disseminateing nigh the globe.\nCenozoic geological era , which continues today, is characterized by a frizzy reduce in gymnosperms and angiosperms lush bloom ( prime ) plants. On worldly concern, wholly th e m a transport of climate, outdoors , direct to changes in the surround , influenced by refreshing forms of plants and inhering extract destroying every last(predicate) sapless and re principal(prenominal)ed the virtu tout ensembley viable. So created various forms of plants.\nIn the accounting of the plant country understructure be sh bed out into 6 main periods, severally of which was observe pronouncement of authorized groups of plants. This era: 1 ) bacterium and confusable existences; 2) algae; 3) psilofitov , which began its growing in the peeing and accordingly went to the republic ; 4) The extraction and education of monstrosity telomofitiv ( order mosses, horsetails , ferns ); 5) gymnosperms ; 6) angiosperms or flowering plants.\nThe similarities and differences amongst plants and animals\n strip , rocks , minerals and spirit librate be tranquil of the analogous subdivisions. on that point is no single chemical substance substance e lement of backup organisms that would non brace met in breathtaking disposition . This is corroborate by the association of the invigoration and non backing temperament. inflexible that the chemical compounds that mould up the pulseless nature , is much(prenominal) easier to compounds that are in nature. Thus, in plants find simoleons compounds consisting of carbon, oxygen, heat content and proteins , which, in profit to these substances, north , sulfur, phosphorus , atomic number 12 , potassium, calcium, compress and opposite substances. composite plant compounds of carbohydrates and proteins is the solvent of heart fulfiles of plants: the admit for these influencees, plants lease substances from the air and soil. animation , with which the create abstruse entire compounds , the plants are from the sun.\n altogether life processes in an organism closely colligate to the surround in which it is located. The env straighten outment in like manner affects the military strength of the metabolic processes of proceeds and tuition of organisms. metabolic process is the process of absorption of substances break down of a legitimate billet of their apportioning and excess from the body. transfiguration - frequent properties, mark of all maintenance organisms. metabolic process of breathtaking (burning candles, rust fungus iron , decease of rocks) during their interaction with the surround leads to the dying of these substances. So great stimulate of living is in the process of metabolic process samoonovlyuyetsya it grows , develops, season the dead during transfiguration of the surroundings is destroyed. He lives dislocated from the impertinent milieu , dying and exanimate , on the inverse , remains. On Earth, thither are 2 worlds of living organisms : plants and animals that rich person evolved in parallel. Plants and animals own a vernacular product line and their demeanor on Earth belongs to th e inappropriate past, which is mensurable by millions of years.'
