Protozoa may also live as mixotrophs, combining a heterotrophic diet with some form of autotrophy. Some protozoa form close associations with symbiotic photosynthetic algae (zoochlorellae), which live and grow within the membranes of the larger cell and provide nutrients to the host. What are protozoa and how are they classified? Learn their characteristics, types, and lifecycle with a diagram and image.
Organisms known as protozoa include a wide range of organisms, most of which are free-living single-celled eukaryotes. Therefore, protozoa fit into the Domain Eukarya. Protozoa Definition Protozoa may be defined as "microscopic acellular animalcules existing singly or in colonies, without tissue and organs, having one or more nuclei".
Protozoa are unicellular eukaryotic microorganisms lacking a cell wall and belonging to the Kingdom Protista. Protozoa reproduce asexually by fission, schizogony, or budding. Some protozoa can also.

What are Protozoa? Protozoa are micro-organisms which have a membrane bound nucleus that can't be categorised as a fungi, animal or plant. Most protozoa are free living, but some are parasitic. They are heterotrophs, meaning that they eat other plants or animals for energy and nutrients. They come in many different shapes and sizes ranging from an Amoeba which can change its shape to Microbiology - Protozoa, Eukaryotes, Unicellular: 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). Like animal cells, protozoa lack
Protozoa ou protozoários é um subreino do Reino Protista. A definição de protista tem mudado bastante ao longo dos tempos. Originalmente criado para incluir todos os organismos vivos que nãoo eram nem plantas nem animais, na atualidade inclui uma grande quantidade de organismos que não podem ser considerados um grupo monofilético.

Abstract Protozoa constitute a convenience group of eukaryotic microbes that are generally defined by their heterotrophism and unicellularity. Free-living protozoa are ubiquitous and found in planktonic, benthic, and soil biomes and a wide variety of protozoa are symbionts with several being important pathogens. The diversity of the protozoa encompasses nearly the entire diversity of Protozoa Protozoa is a general term applied to a large and diverse group of eukaryotic unicellular motile microorganisms that belong to what is now known as the kingdom Protista. Members of this kingdom can be free-living and saprophytic, commensal, symbiotic, or parasitic. The cell contains a variety of organelles, but no cell wall, and cells vary greatly in size and shape among different
