Question

Which of the following is NOT a function of mucilage in bacteria?
A)protection against a host's immune system
B)facilitating acquisition of mineral nutrients
C)acting as a flotation device
D)nitrogen fixation
E)holding cells together for communication among them

Accepted Answer

Mucilage in bacteria can serve various functions such as protection from host immune system, facilitating nutrient acquisition, acting as a flotation device, and holding cells together for communication. Nitrogen fixation is not a function of mucilage. Nitrogen fixation is a process in which certain bacteria convert atmospheric nitrogen into biologically useful forms that are unavailable to plants and animals otherwise.
