Question

Your teacher gives you an unknown protist to classify that is currently inactive. The protist appears to have long lash-like appendages protruding from its cell surface. Which kind of locomotion can we expect from this protist?(1 point)ResponsesThe appendages of this protist will move back and forth like a wagging tail to actively propel the protist forward.The appendages of this protist will move back and forth like a wagging tail to actively propel the protist forward.The appendages of this protist will move in a dragging motion that actively pulls the protist forward.The appendages of this protist will move in a dragging motion that actively pulls the protist forward.The appendages of this protist are not functional, and the protist moves passively via environmental forces.The appendages of this protist are not functional, and the protist moves passively via environmental forces.The appendages of this protist will move in a sweeping motion like oars to actively propel the protist forward.

Answer 1

Based on the description of the unknown protist having long lash-like appendages protruding from its cell surface, it is likely that these appendages are flagella. Flagella typically move in a whip-like or undulating motion, allowing the organism to propel itself through its environment.

Therefore, the most suitable response would be:

The appendages of this protist will move back and forth like a wagging tail to actively propel the protist forward.

This describes the typical movement associated with flagella, which is effective for locomotion in many protists.
