- The main role of bacterial endospores is to ensure survival during unfavorable environmental conditions.
- Endospores are highly resistant structures formed by some bacteria to protect their genetic material from extremes such as heat, desiccation, chemicals, and radiation.
- This allows the bacteria to remain dormant until conditions become favorable again for growth.
- Endospores do not facilitate nutrient absorption, transfer genetic material, or enhance motility, but serve primarily as a survival mechanism.
