Question

Pellicle is a flexible, protein-rich layer found in:

• A. Slime mould
• B. Chrysophytes
• C. Euglenoid / Euglena
• D. Sporozoa

Hint:

Remember: \[ \boxed{\text{Euglenoids} \rightarrow \text{Flexible pellicle}} \] They are photosynthetic in the presence of light but become heterotrophic in the absence of light, making them mixotrophic organisms.

Answer 1

The Correct Option is C

A pellicle is a flexible, protein-rich layer found just beneath the plasma membrane in Euglena, a protist of Kingdom Protista. Unlike the rigid cell wall of plants or fungi, the pellicle allows Euglena to change its shape through a movement called metaboly or euglenoid movement.
