Study Notes
Cell Division and Reproduction
- Binary fission involves dividing a single cell into two cells
- Budding is a method of asexual reproduction in certain fungi and some bacteria
Spores and Dormancy
- Endospores are metabolically inactive structures that allow certain cells to enter a dormant state
- Spores are reproductive cells
Population Growth
- Generation time refers to the time it takes for a cell to divide
- Exponential growth occurs when the rate of growth (reproductions) increases by a constant proportion
Bacterial Growth Curve
- Closed batch system: bacteria are grown in a sterile growth medium with a set amount of organic and inorganic nutrients
- Lag phase: a delay that occurs while cells adjust to their new environment
- Log phase: period of rapid exponential growth
- Stationary phase: nutrients are depleted, waste accumulates; population growth rate levels off
