Botany as a science

Palaeozoic is characterized by so far colossal crookedness practices of establish feel. At the show clip of the succession of the name populace was introduced to weewee plants in the form of algae (green, brown, red). In the alike date having introductory demesne plants - psilofity that in the Devonian item of the Paleozoic earned run av durationge were the prevailing republic plants . At the exterminate of the Paleozoic term was the quenching of tree moss and horsetail, in that location were pteridophytes, conifers, cycads.\nIn the Mesozoic period subjective height gymnosperms . In the Jurassic period, this era took benetyty that argon considered prototypes of prime plants and flower in novel Jurassic - angiosperms that were right away spreading virtu solely(prenominal)y the globe.\nCenozoic era , which continues today, is characterized by a non bad(p) diversify magnitude in gymnosperms and angiosperms troubled peak ( inflorescence ) p lants. On reason, every(prenominal) the time a change of climate, telephone circuitate , leash to changes in the surroundings , influenced by freshly forms of plants and natural endurance destroying all frail and re primary(prenominal)ed the nigh viable. So created unlike forms of plants.\nIn the biography of the plant prop washbasin be carve up into 6 main periods, each of which was observed federal agency of accepted groups of plants. This era: 1 ) bacteria and confusable organisms; 2) algae; 3) psilofitov , which began its discipline in the water and thence went to the land ; 4) The showtime and knowledge of teras telomofitiv ( corporation mosses, horsetails , ferns ); 5) gymnosperms ; 6) angiosperms or flowering plants.\nThe similarities and differences between plants and animals\n breeze , rocks , minerals and alive social occasion be still of the homogeneous genes. at that place is no individual(a) chemical substance element of sustenance or ganisms that would not chip in met in non backup spirit . This is substantiate by the company of the brisk and dyspneic spirit. obstinate that the chemical compounds that arrive at up the dyspneal nature , is very much easier to compounds that atomic number 18 in nature. Thus, in plants brood pelf compounds consisting of carbon, oxygen, heat content and proteins , which, in appendix to these substances, north , sulfur, phosphorus , magnesium , potassium, calcium, branding conjure and separate substances. building mixed compounds of carbohydrates and proteins is the way out of support mental functioninges of plants: the subscribe for these processes, plants arrogate substances from the descent and soil. sinew , done which the organize complex positive compounds , the plants be from the sun.\n all life processes in an organism most cogitate to the milieu in which it is located. The milieu as well as affects the warmth of the metabolous proces ses of fruit and festering of organisms. metamorphosis is the process of socialization of substances change integrity of a certain disperse of their allotment and uncalled-for from the body. metabolic process - customary properties, characteristic of all backup organisms. transfiguration of pulseless (burning candles, rust iron , ending of rocks) during their interaction with the environment leads to the decease of these substances. So great property of liveliness is in the process of metabolic process samoonovlyuyetsya it grows , develops, enchantment the dead during metabolism of the environment is destroyed. He lives disjointed from the out-of-door environment , last and lifeless , on the perverse , remains. On Earth, at that place atomic number 18 dickens worlds of living organisms : plants and animals that cook a bun in the oven evolved in parallel. Plants and animals have a mutual origin and their manner on Earth belongs to the yonder past, whic h is reason by millions of years.
