This article describes a philosophy of an arising multicellularity on the basis of division of functions between cells. Laws of the division are discussed in elementary multicellularity units, called histions. There is a variety of the histions that have different social structures. Several parameters have been proposed to describe them quantitatively and to systematize them by means of a periodic table. Consideration is given to the rules that govern polymerization of histions as well as the formation of regular cellular networks using them. It is shown that these types of networks could serve as biological tissue models that enable one to predict the tissue development. It has been found that arising multicellularity can result in a drastically decreased metabolites production per cell and thus creates the need in their economically justified unequal distribution.
