Document Summary

Lag phase: can last from minutes to days (variable in its time) depending on the species and the physiological history of the starting cells of the culture: little to no cell division in this phase as the slope on the graph will be flat, no increase in cell numbers, however there is much metabolic activity including dna synthesis, Log phase: cells that have been prepared to divide in lag phase can: cell number doubles at a rate characteristic of organism in now undergo division in log phase/exponential phase a given set of conditions (temperature, nutrients, etc, growing population will use up nutrients and excrete waste products. Each daughter cell will receive a full copy or will not survive: in prokaryotic dna synthesis (chromosome duplication) and the rest of cell metabolism occur concurrently through the life cycle of the cell *this does not occur in eukaryotic cells* daughter cells is much more complicated in eukaryotes much more dna is present o.
