A) They are uniformly dispersed throughout the cell.
B) They contain the structural polymer cellulose.
C) Their organization is consistent with structures that could be used in locomotion.
D) They play a role in digestion.
E) They are composed primarily of peptidoglycan.

Quizplus · Accepted Answer

The organization of the internal flagella in the axial filament is consistent with structures that could be used in locomotion. This means that they are capable of propelling the prokaryote through its environment. The other options are incorrect: A is false because the internal flagella are not uniformly dispersed throughout the cell; B is false because cellulose is a structural polymer found in plants and some algae, not prokaryotes; D is false because there is no evidence that the internal flagella play a role in digestion; and E is false because peptidoglycan is a structural component of the bacterial cell wall, not the axial filament.
