Protists may be unicellular or multicellular. They vary in how they get their nutrition, morphology, method of locomotion, and mode of reproduction. Important structures of protists include contractile vacuoles, cilia, flagella, pellicles, and pseudopodia; some lack organelles such as mitochondria. Taxonomy of protists is changing rapidly as relationships are reassessed using newer techniques.

Eukaryotic cell morphologies vary greatly and may be maintained by various structures, including the cytoskeleton, the cell membrane, and/or the cell wall The nucleolus in the nucleus of eukaryotic cells is the site of ribosomal synthesis.

Cilia are abundant, while flagella are fewer, aiding in functions such as sperm movement and clearing mucus in respiratory systems. Notably, almost all mammalian cells have a primary cilium that is important for sensory functions, with defects linked to diseases like polycystic kidney disease.
