can say that living organisms - is a complex system that performs various functions necessary for normal life.They consist of cells.Therefore, divided into single-celled and multicellular.It forms the basis of the cell of any organism, regardless of its structure.
unicellular organisms have only one type of cell.In multicellular organisms represented by different cell types, which differ in their functional value.The study of cells involved in cytology, which includes science biology.
cell structure is almost the same for each type.They vary in functionality, size and shape.The chemical composition is also typical of all the cells of living organisms.The cell comprises a main molecules: RNA, proteins, DNA, polysaccharides and lipids elements.Almost 80 percent of the cell is water.In addition, it is composed of sugars, nucleotides, amino acids and other products of the processes occurring in the cell.
structure of the cell of a living organism is composed of many components.The surface membrane of cells.It allows cell penetration only certain substances.Between cell membrane and intercellular substance is liquid.This membrane is the intermediary in the exchange processes occurring between the cell and extracellular fluid.
main component of the cell is the cytoplasm.This material was a viscous, semi-solid consistency.It contains organelles, which perform a range of functions.These include the following components: the cell center, lysosomes, nucleus, mitochondria, endoplasmic reticulum, ribosomes and complex Goldzhi.Kazhdy of these components is necessarily included in the structure of the cell.
whole cytoplasm consists of a plurality of tubular cavities and which constitute the endoplasmic reticulum.The whole system synthesizes, stores and promotes organic compounds that are produced by cells.Endoplasmic reticulum and is involved in protein synthesis.In addition it
protein synthesis participate ribosomes which contain RNA and protein.Golgi complex affects the formation of lysosomes and accumulates the organic substance.This special cavities with bubbles at the ends.
Cellular Center contains two calf involved in cell division.The cell center is located directly next to the nucleus.
So gradually we got to the main component in the structure of the cell - the nucleus.This is the most important part of the cell.It contains the nucleolus, proteins, fats, nucleic acids, carbohydrates, and chromosomes.All of the inner core is filled with nuclear sap.All information about heredity contain chromosomes.The structure of the cells of the human body involves the presence of 46 chromosomes.Germ cells are made up of 23 chromosomes.
The structure of the cells and lysosomes are included.They clean the cage of dead particles.
cells, besides the main components, and some of the compounds contain organic and inorganic nature.As already mentioned, the cell consists of 80 percent of water.Another inorganic compound, which is included in its composition, are salts.Water plays an important role in the life of the cell.It is the principal participants in chemical reactions, as a carrier of substances and output of cells harmful compounds.Salts contribute to the proper distribution of water in the cell structure.
Among the organic compounds present: hydrogen, oxygen, sulfur, iron, magnesium, zinc, nitrogen, iodine, phosphorus.They are essential for conversion into complex organic compounds.
cell - is the main component of every living organism.Its structure - a complex mechanism, in which there should be no any glitches.Otherwise, it will lead to the same processes.
