The figure below shows a Paramecium,a single-celled freshwater protist.The hairlike structures visible on the Paramecium allow it to move.These structures are ________. 
A)microfilaments 
B)intermediate filaments 
C)flagella 
D)cilia

Quizplus · Accepted Answer

The hairlike structures visible on the Paramecium are called cilia, which enable the Paramecium to move. Option A (microfilaments) and B (intermediate filaments) are different types of cytoskeletal filaments, but they do not directly contribute to the movement of the Paramecium. Option C (flagella) are similar to cilia, but they are typically longer and less numerous; Paramecium have numerous cilia, not flagella.
