A scientist is studying a protist and records the following information about it:Cell has a nucleusHas a flagellaProduces oxygenFound in salt water

Producing oxygen indicates that the protist performs photosynthesis, so it is plant-like. Dinoflagellates are plant-like protists that commonly live in salt water and have flagella. Having a flagellum alone does not make a protist animal-like, since dinoflagellates can have flagella too.
