Damian observes a bacterium moving over a solid surface and transmission electro

Question

Damian observes a bacterium moving over a solid surface and transmission electron microscopy reveals the presence of both flagella and pili. He assumes that one of these structures is responsible for surface motility. a. Is Damian making a good assumption? Why or why not? (1 point) b. Design additional experiments to help Damian determine how this bacterium moves over surfaces. Be sure to explain how the results of each experiment will indicate which type of surface motility is used by the bacteria. (2 points)

Explanation / Answer

Answer- (1) Damian is making good assumption because on moving through solid suface one structure will help in anchoragement and other struture will make bacteria move . So pilli help in surface attachment thus flagella will make bacteria move .

Answer (2) Another experiment is that bacteria made to move on different surfaces on liquid surface and other than solid. In liquid surface swimming movement is seen among bacteria but gliding movement on other .
