Question

Pellicle is the covering of

• A. Paramoecium
• B. Plasmodium
• C. Monocystis
• D. All of the above

Answer 1

Answer: (D)

All of the above

• The pellicle is a thin layer supporting the cell membrane in various protozoa.
• The pellicle is stiff to maintain the paramecium's shape and provide stability but it is also flexible to allow movement.
• It also acts as an attachment site for external organelles such as cilia. Paramoecium, Plasmodium and Monocystis contain pellicle.
• Hence, the pellicle is the covering of Paramoecium, Plasmodium and Monocystis.
• So, the correct answer is 'All of the above'.
