You get to learn interesting details about the world of microbes, from the diseases they cause to the essential roles they play in ecosystems and industry. Then, work in a top-secret underground biotechnology lab and help develop a new strain of bacteria that can clean up environmental contamination.
After completing this tutorial, you will be able to complete the following:
What occurs during sporulation?
~ During sporulation, a bacteria cell copies its DNA and protects it with cytoplasm and a cellular wall.
What is the product of sporulation?
~ An endospore is created from sporulation.
What are the characteristics of endospores?
~ Endospores are resistant to extreme temperatures, pressure, chemicals, and radiation because of their thick cellular wall.
What happens after an endospore is released from its "mother" cell?
~ After an endospore is released from its "mother" cell, it takes in water, swells, and forms a bacterium, which reproduces by binary fission and forms new bacterial cells. This can only happen if environmental conditions are ideal.
What is the advantage of endospore production to bacteria?
~ Bacteria produce endospores as a type of adaptation to survive in unfavorable conditions like extreme temperatures. Sporulation is not a type of reproduction.
