The highly complex cell structure that we have already discussed is the most explicit and profound expression of that teleonomic character. Pretty well every element within that bacterium can be associated with a particular cell function, in much the same way that the individual components of a clock—pendulum, cogs and wheels, springs, hands, cabinet, etc.—can also be associated with a particular function, except that within the cell the structural complexity and intricacy is orders of magnitude greater.
