Question

Which group of organisms possesses a protein rich layer called pellicle?

• A. Chrysophytes
• B. Euglenoids
• C. Dinoflagellates
• D. Slime moulds
• E. Protozoans

Answer 1

Answer: (B)

Euglenoids

• Euglenoids are unicellular flagellate protists.
• They are without the cell wall.
• The body is covered by thin and flexible pellicle which is a protein-rich layer. The pellicle has oblique but parallel stripes called myonemes.
• The pellicle is composed of fibrous elastic protein, a small amount of lipid and carbohydrates and maintains a definite shape. It is flexible enough to permit temporary changes in body shape. so, option B is correct
