Question

Which of the following structures is NOT used by protists for motility?

Question 4 options:

cilia


holdfast


flagella


pseudopods

Answer 1

The structure that is NOT used by protists for motility is the **holdfast**. A holdfast is a structure that anchors an organism to a surface, but it does not facilitate movement. In contrast, cilia, flagella, and pseudopods are all involved in the locomotion of various protists.
