Figure 17-31Cell size control through control of the cell cycle in yeasts

These graphs show the relationship between growth rate, cell size, and cell cycle time. (A) If cell division continued at an unchanged rate when cells were starved and stopped growing, the daughter cells produced at each division would become progressively smaller. (B) Yeast cells respond to some forms of nutritional deprivation by slowing the rate of progress through the cell cycle so that the cells have more time to grow. As a result, cell size remains unchanged or is reduced slightly. (A unit of time is the cycle time observed when nutrients are in excess.)
