The functions of a pellicle are diverse and include:
Protection: The pellicle can act as a barrier against physical and chemical insults, protecting underlying cells or tissues. Structural Support: In protozoa, the pellicle helps maintain the cell’s shape and structural integrity. Adhesion: In bacterial biofilms, the pellicle facilitates the adhesion of bacteria to surfaces and to each other, promoting community stability. Regulation: The pellicle can participate in various regulatory processes, such as controlling the exchange of substances between the cell and its environment.
