Aug 3, 2023 · Protozoa are unicellular eukaryotic microorganisms with a membrane-bound nucleus and other organelles. They are diverse, widespread, and can be free-living, symbiotic, or parasitic in various aquatic and terrestrial habitats.
Protozoa, or protozoans, are single-celled, eukaryotic microorganisms. Some protozoa are oval or spherical, others elongated. Still others have different shapes at different stages of the life cycle. Cells can be as small as 1 μm in diameter and as large as 2,000 μm, or 2 mm (visible without magnification).
