Solution:

Pellicle is the thin outer covering composed of proteins that protect and maintain shape and flexibility of certain unicellular organisms like euglenoids e.g., Euglena. It is transparent and in ciliates e.g., Paramecium contains small pores through which cilia emerge. Not all protozoans have pellicle though.
