what is the motion of paramecium through the water?
A photograph of Paramecium is shown right below. Movement The outer surface of the cell is covered with many hundreds of tiny hair-like structures called cilia. These act like microscopic oars to push through the water, enabling the organism to swim. The speed of motion is about four times its own length per second. It moves so quickly that microscopists have to add a thickening agent to the water to slow it down to study it. As it moves through the water it rotates on its axis and small particles of debris and food are collected and swept into the gullet. If Paramecium comes across an obstacle, it stops, reverses the beating of the cilia, swims backwards, turns through an angle and moves forward again on a slightly different course. Feeding
