levels of organization of living matter - a symbol adopted for the classification of all living organisms on our planet.Wildlife Earth is truly diverse.The organisms may take a variety of sizes, from the simplest single-celled microbes and, going to multicellular creatures, and ending with the largest animals on Earth - whales.
evolution on earth is going on in such a way that organisms evolved from simple (literally) to the more complex.Thus, the arising, disappearing, new perfected in the course of evolution, taking a more whimsical look.
to organize an incredible number of living organisms and have been introduced levels of organization of living matter.The fact is that, despite differences in appearance and structure, all organisms living nature have in common: they are somehow composed of molecules that are composed of repetitive elements, in one sense or another - the general functions of the bodies;they feed, breed, age and die.In other words, the properties of a living organism, despite the differences in appearance are similar.Actually, focusing on these data, it is possible to trace how the evolution of our planet.
Thus, we consider the levels of organization of living matter in more detail.The first level covers all living organisms without exception.What he (level) above, the growing number of wildlife is eliminated.
1. Molecular level is common to all organisms.Under this level invisible to the naked eye occurring processes that take place in any living organism: synthesis and breakdown of nutrients, building or safeners.This is the level of large molecular compounds (proteins, nucleic acids and so on. D.)
2. supramolecular or subcellular. level at which the structuring of molecules in the cell organelles: cell membrane, chromosomes, the vacuole, the nucleus, and so on. D.
3. Cell. This level is represented as a matter of elementary functional units - cells.
4. organ-tissue level. It is at this level are formed all the organs and tissue of a living organism, regardless of their complexity: the brain, tongue, kidney, and others. It should be borne in mind that the fabric - a set of cells, united by a common structure and function.Authority - part of the body, "duty" which includes the implementation of a clearly defined function.
5. ontogenetic or organismal level. At this level, a variety of functional elements are combined into a complete organism.In other words, this level has already presented a holistic individual of any kind.
6. Population-specific. organism or individuals that have a similar structure, function, and a similar appearance, and thus belonging to the same species are included in one population.In biology, population understand the totality of all individuals of this species.In turn, they form a unified and genetically isolated system.The population lives in a certain place - range and, as a rule, does not intersect with other species.Type, in turn, is an aggregate of all populations.Living organisms can interbreed and produce offspring only within its kind.
7. biocenotic. level at which living organisms are combined in ecosystems - all the populations living in a particular area.Belonging to one or another form, in this case does not matter.
8. biogeocenotic. This level is due to the formation biogeocenosis, ie aggregate biocenosis and non-living factors (soil, climate) in the region where the biocenosis lives.
9. Biosphere. level, uniting all living organisms on the planet.
Thus, levels of organization of living matter into nine points.This classification determines the current in modern science systematization of living organisms.
