agencies plural of organismoUn be live or body is a structural material of complex organization, which involved molecular communication systems listed it internally and with the environment in an exchange of matter and energy in a way that is orderly, having the ability to perform the basic functions of life which are the nutrition, the relationship and reproductionso that human beings Act and work on their own without losing its structural level until his death
A multicellular or multicellular organism is one that is made up of 2 or more cells, as opposed to single-celled organisms ( protists and bacteria, among many other ) that you meet all their vital functions in a single cell.Multicellular - like plants, animals, and Brown algae organisms - arise from a single cell, which multiplies generating an organism. The cells of multicellular organisms are differentiated to perform specialized functions, and reproduce by mitosis and meiosis. To form a multicellular organism, these cells need to identify and bind to other cells. Multicellular organisms have permanent cellular connections, i.e., cells have lost their ability to live alone, requiring the Association, but this must occur in such a way that lead to different cell types that generate cellular organization in tissues, organs, and systems, thus forming a completo.1 organism multicellular organisms are the result of the union of single-celled individuals through formation of coloniesstrands or aggregation. The multicelularidad has evolved independently in Volvox and some green algae flageladas.2 3Un set of differentiated from similar cells that carry out a specific function within a multicellular organism is known as a fabric. However, in some unicellular microorganisms, such as the logarithmic or some microorganisms that form biofilms, differentiated cells are although differentiation is less pronounced, which is typically found in multicellular organisms.Multicellular organisms must tackle the problem of regenerating the whole organism from germ cells, under study by the biology of the development. The spatial organization of differentiated cells as a whole Anatomy studies.Multicellular organisms may suffer cancer, when he fails to regulate the growth of cells within the framework of normal development. Examples of multicellular organisms are very varied, and can go from a fungus to a tree or an animal:
