The measurable size of nutrients needed for a cell to thrive and divide has been discovered. Divisional function of bacteria is triggered once it reaches a certain size and is in response to the general growth law. It is important to understand that bacteria grow faster and bigger when the quality of nutrients available to them is better. Extensive research on the significance of the growth law has been preformed, using the model organism Escherichia coli. The discoveries began with noticing the cell size remained constant when cells began to replicate their genetic material. This unchanged cell size is a representation of the fundamental unit of cellular resources needed in order to start growth and the cell cycle. The growth inhibition experiments that were carried out were given in part to thorough cell sampling of large populations of bacteria. The quantitative aspects of biology are shaping the field and promising much greater things for the future in research.
