Question

match the phase of the bacterial growth curve with its description.
1 stationary growth phase
2 exponential growth phase
3 death phase
4 lag phase
match each of the options above to the items below.
phase during which nutrient depletion and accumulation of wastes begin to slow cell growth such that the rate of cell increase equals the rate of cell death
phase during which cells are growing very quickly, at their maximum rate of cell division
adjustment period during which cells are dividing slowly while they adjust to growth conditions
nutrient depletion and waste accumulation prevent cell growth and cells die exponentially

Explanation:

1. For the description "Phase during which nutrient depletion and accumulation of wastes begin to slow cell growth such that the rate of cell increase equals the rate of cell death", this matches the Stationary growth phase (1) because in the stationary phase, growth and death rates balance.
2. For "Phase during which cells are growing very quickly, at their maximum rate of cell division", this is the Exponential growth phase (2) as exponential phase is when cells divide rapidly.
3. For "Adjustment period during which cells are dividing slowly while they adjust to growth conditions", this is the Lag phase (4) since lag phase is the initial adjustment period with slow division.
4. For "Nutrient depletion and waste accumulation prevent cell growth and cells die exponentially", this is the Death phase (3) as death phase involves exponential cell death due to harsh conditions.

Answer:

1. Phase during which nutrient depletion and accumulation of wastes begin to slow cell growth such that the rate of cell increase equals the rate of cell death: 1. Stationary growth phase
2. Phase during which cells are growing very quickly, at their maximum rate of cell division: 2. Exponential growth phase
3. Adjustment period during which cells are dividing slowly while they adjust to growth conditions: 4. Lag phase
4. Nutrient depletion and waste accumulation prevent cell growth and cells die exponentially: 3. Death phase
