Paramecium (Amoeba proteus) is a protozoan, a single-celled organism, not a plant. They are a type of protoplasmic worm that usually lives in fresh water and feeds on bacteria, yeast and other tiny organic matter.
The main body of Paramecium is composed of a transparent substance called protoplasm, which has no fixed shape and structure. They can change their shape to move and prey, usually by extending protrusions like pseudopodia to move.
Paramecium is a very simple but magical creature with a short life cycle but very rich life activities. In scientific research, Paramecium is also widely used as experimental material to explore basic problems in cells, physiology, etc.
