Bacillus anthracis, the bacterium that causes the deadly disease anthrax produces thick endospores. What is the significant role of spore formation in the reproductive cycle of this bacterium? Helps bacteria multiply quickly and grow in colonies Helps bacteria survive extreme conditions and later develop into fully functional bacterial cells Helps bacteria develop resistance to antibiotics
The answer is Helps bacteria survive extreme conditions and later develop into fully functional bacterial cells. Endospores are dormant and non-reproductive structures characteristic for bacterial phylum Firmicute, which include genus Bacillus. Those endospores are not real spores, such as plant spores. They are dormant form of bacteria which formation is triggered by some unfavourable environmental conditions. They help bacteria survive those extreme conditions so they could, in favourable conditions, develop into fully functional bacterial cells.
