Document Summary
Prokaryotes replicate by binary fission (divide into 2 cells) Process continues as long as there is a supply of nutrients and no build-up of products. Time required for one binary fission is called doubling or generation time. Ideal curve is j-shaped; exponential growth) because nutrients are unlimited. Lag phase: no cell division occurs, lots of metabolic activity such as dna synthesis and transport of nutrients into cell. Log phase: cell division begins (maximum rate); uses up nutrients and excretes waste products. Stationary phase: cell division and cell death occur at same rate because of lack of nutrients and accumulation of waste products. Death phase: cell lysis due to damaged cell walls, which may be because of accumulated toxic byproducts. In prokaryotes, bacterial chromosome (dna and genetic material) is replicated. A septum (barrier) forms in a dividing prokaryotic cell (process is called invagination. ) Cell walls are synthesized and daughter cells separate.
