They represent the vast diversity of eukaryotic organisms, and thus span the breadth of possibilities with regard to life history traits. They can be heterotrophs or autotrophs, unicellular to massively multicellular (though rarely with any specialized tissue organization), and can be found across ecosystems worldwide. Photosynthesis within protists is the result of multiple separate endosymbiotic events.

Some biologists propose classifying them as acellular due to their intricate organization. Ciliates have a small diploid micronucleus that contains their genome and a large polyploid macronucleus for gene functions. They reproduce sexually, promoting genetic diversity.
