Simple cells show a lack of organization. In living matter there is a tendency for paths of energy to become permanent, and it is in this tendency that we find the beginning of structuralization of function or the formation of definite tracts by energy. These energy channels become permanently organized, the organization being transmitted to form part of the organism. Later, organization follows a definite plan and we find head and tail ends, etc. Experiments show that energy is highest at the point where the stimulus is received. The tapering of energy intensity is called the dynamic gradient. From these conclusions it is suggested that the single-celled organism has a head in effect, if not in structure, and the beginning
