the paramecium uses cilia, which are tiny hair-like structures, for locomotion. on the other hand, amoeba uses pseudopodia, which are extensions of the cell's cytoplasm, to mo â¦ ve.+ 2 others found this useful.hey move with the help of microscopic hair-like structures called cilia, which act like oars to push them through the water. They swim by rotating slowly and changing directions often. If the Paramecium comes upon an obstacle, it stops, swims backwards, and then angles itself forward on a slightly different course.
Most eukaryotic cells contain a complex network of protein fibers called the cytoskeleton. It forms a framework for the movement of organelles around the cytoplasm-most of the organelles are attached to the cytoskeleton. The network consists of protein microfilaments, intermediate filaments, and microtubules. The cytoskeleton provides an important structural framework for: 1  Cell shape. 2  For cells without cell walls, the cytoskeleton determines the shape of the cell. 3  This is one of the functions of the intermediate filaments. 4  Cell movement.
