Question

Identify the type of movement described.


are long, thread-like extensions that grow from the protists to reach nutrients.

are long whip-like extensions used to move the protists to the nutrients needed.

are temporary foot-like extensions used to propel protists forward slowly through suctioning movement.

are hair-like extensions used like oars to propel the protists to nutrients.

Answer 1

- Axopodia (or filopodia): long, thin, thread-like extensions protists send out to reach or capture nutrients (seen in heliozoans, radiolarians).
- Flagella: long, whip‑like tails used to swim toward nutrients.
- Pseudopodia (amoeboid movement): temporary, foot‑like extensions used for slow crawling/suction (amoebas).
- Cilia: short, hair‑like projections that beat like oars to move the protist (e.g., Paramecium).
