👉 A type of protozoan, Physarum is a member of the family Pyrgidae, which includes other protozoans. It is characterized by its long, slender body and a small, flat mouth. The body is composed primarily of an outer membrane that covers the cell wall, allowing for movement. The cell wall of Physarum contains a series of hydrophilic (water-loving) molecules called cellulose, which help in maintaining the organism's shape and stability.
