Protists are eukaryotic cells (eukaryotes). Protists have a mitochondrion. This means that they have a membrane-enclosed nucleus and other cell organelles. Some are single-celled; others are syncytial (coenocytic; essentially a mass of cytoplasm); and still others are multicellular. Protists is a catch-all term used to describe all eukaryotic organisms — meaning those that have cells with nuclei — besides animals, plants, and fungi.Examples include the unicellular animal-like protozoa, the fungus-like slime molds, and the plant-like protophyta.

Protists are a taxonomically inhomogeneous group of mostly unicellular eukaryotic microorganisms. Decompose dead organisms and absorb their nutrients / slime molds and water molds . For classification, the protists are divided into three groups: animal-like protists, plant-like protists, and fungi-like protists. Protists evolved into the other three types of eukaryotes, including fungi. Other than that, these two types of eukaryotes are very different. D) They have a nucleus. Protists share only a few general characteristics. The major steps of eukaryotic evolution will be in focus. The pathogen that causes giardia is in this group. Structural and Functional Diversity in Protists. What process do they use to make food? The nuclear genome of eukaryotes is related most closely to the Archaea, so it may have been an early archaean that engulfed a bacterial cell that evolved into a mitochondrion. Because protists are eukaryotes, their cell or cells have a nucleus and membrane bound organelles. Protists include the single-celled eukaryotes living in pond water (Figure 13.3.1), although protist species live in a variety of other aquatic and terrestrial environments, and occupy many different niches. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. I had to look it up (never heard the term before), so many thanks for asking, Azn!
