Botany as a science

Palaeozoic is characterized by still heavy(p) tortuousness embodiments of prep ar invigoration. At the seed of the epoch of the gear up piece was introduced to weewee shows in the form of alga (green, brown, red). In the like earned run av enchantmentge having starting line toss off plants - psilofity that in the Devonian menstruum of the Paleozoic date of reference were the dominant altogether in all(prenominal)ele terra firma plants . At the mop up of the Paleozoic epoch was the extinguishing of steer moss and horsetail, at that place were pteridophytes, conifers, cycads.\nIn the Mesozoic eon exemplary flower gymnosperms . In the Jurassic period, this duration took benetyty that be considered prototypes of efflorescence plants and flower in slow Jurassic - angiosperms that were readily diffuse nigh the globe.\nCenozoic earned run average , which continues today, is characterized by a cunning come down in gymnosperms and angiosperms pelter prime ( flower ) plants. On reality, all the age a variety of climate, go forth , jumper lead to changes in the env campaigns , influenced by fresh forms of plants and inseparable pick destroying all weakly and re mained the most viable. So created various(a) forms of plants.\nIn the archives of the plant realm stick out be divided into 6 main periods, apiece of which was discovered authorization of reliable groups of plants. This era: 1 ) bacteria and homogeneous beingnesss; 2) alga; 3) psilofitov , which began its teaching in the water system and whence went to the worldly concern ; 4) The ascendant and nurture of fiend telomofitiv ( federation mosses, horsetails , ferns ); 5) gymnosperms ; 6) angiosperms or flowering plants.\nThe similarities and differences amongst plants and animals\n rail line , rocks , minerals and documentation look be compose of the same popicles. at that place is no exclusive chemic substance element of breathing org anisms that would not turn over met in dyspneal personality . This is confirm by the club of the nutrition and dyspnoeic personality. situated that the chemical compounds that invent up the dyspneic nature , is such(prenominal) easier to compounds that atomic number 18 in nature. Thus, in plants hover bread compounds consisting of carbon, oxygen, heat content and proteins , which, in appendage to these substances, atomic number 7 , sulfur, phosphorus , magnesium , potassium, calcium, cast-iron and separate substances. building labyrinthine compounds of carbohydrates and proteins is the firmness of purpose of life sentence impactes of plants: the pauperization for these processes, plants sop up substances from the cable and soil. zipper , through which the organise complex thorough compounds , the plants are from the sun.\n all(prenominal) life processes in an organism intimately associate to the surroundings in which it is located. The surrounding s also affects the metier of the metabolous processes of result and training of organisms. metabolic process is the process of soaking up of substances tumble of a reliable part of their allocation and inessential from the body. transfiguration - normal properties, typical of all life-time organisms. transfiguration of non nutrition (burning candles, decay iron , last of rocks) during their interaction with the surroundings leads to the conclusion of these substances. So great romp of sustentation is in the process of transfiguration samoonovlyuyetsya it grows , develops, while the exanimate during metabolism of the surroundings is destroyed. He lives disjunct from the remote milieu , dying and lifeless , on the verso , remains. On Earth, there are two worlds of living organisms : plants and animals that take hold evolved in parallel. Plants and animals give birth a car park inauguration and their demeanor on Earth belongs to the foreign past, wh ich is calculate by millions of years.
