Question

A protective layer made of rigid or elastic protein strips surrounding the cell membrane of euglenoids is a

a. flagellum.
b. cell wall.
c. pellicle.
d. pseudopodium.
e. gullet.

Answer 1

The protective layer surrounding the cell membrane of euglenoids is called the pellicle. It is a flexible, protein-based structure that provides rigidity and strength to the cell.

Step-by-step explanation:

The protective layer made of rigid or elastic protein strips surrounding the cell membrane of euglenoids is called the pellicle. It is a flexible, protein-based structure that provides rigidity and strength to the cell, similar to a cell wall but more flexible. The pellicle can be seen as delicate parallel striations over the surface of the entire cell.
