Study Notes
Spores and Endospores
- Spores are dormant, tough, and non-reproductive structures produced by certain bacteria
- Specifically, endospores are a type of spore formed by bacteria
- Endospores form in response to stress, such as nutrient depletion
- The primary function of endospores is survival, not reproduction
- Endospores can withstand extreme conditions, allowing them to survive in harsh environments
- When conditions become favorable, endospores can germinate to become a vegetative cell
