growth, the increases in cell size and number that take place during the life history of an organism. Growth is seldom random. Rather, it occurs according to a plan that eventually determines the size and shape of the individual. Growth may be restricted to special regions of the organism, such as the layers of cells that divide and increase in size near the tip of the plant shoot. Or the ...

At a low concentration, the substrate is the limiting factor for growth (Fig. 19.14A). The Fig. 19.14B represents the growth rate for a given substrate concentration (by plotting ...
Stationary phase results from a situation in which growth rate and death rate are equal. The number of new cells created is limited by the growth factor and as a result the rate of cell growth matches the rate of cell death. The result is a “smooth,” horizontal linear part of the curve during the stationary phase.
