How Are Protists Related to Other Eukaryotes?

Protists are eukaryotes that are not members of the plant, animal, or fungi kingdoms. How are protists related to other eukaryotes? ... Some protists move by changing their cell shape, and some move by means of specialized organelles. Other protists do not move actively but are carried by wind, water, or other organisms.

Why are protists grouped with eukaryotes?

The only real constant rule is that all protists are eukaryotes, meaning that they are organisms with more complex cells than bacteria. ... Most protists have a single defined nucleus holding the bulk of their DNA, though some ciliates have multiple nuclei and flagellates do not have a defined nucleus.

Did protists evolve from eukaryotes?

Scientists think that protists are the oldest eukaryotes. Protists most likely evolved from prokaryotic cells, as explained by the endosymbiotic theory. This theory is well-supported by evidence.
