Do protozoans have a cellular nucleus. When these conditions are unfavorable such as when food is scarce most species are able to enter an inactive phase where cells become non-motile and secrete a surrounding cyst that prevents desiccation and protects the cell from extreme temperatures.
Nucleus plays an important role in the process.
Do protozoans have a nucleus. It may be solid because the macronucleus of ciliates is darkly-staining without significant vesiculation What is the basis for classification of protozoa. However cell biological analysis of protozoans reveals that in some cases multiple nuclei are the norm. Movement in protista is dependent upon certain physical characteristics.
In protozoa other than ciliates the nucleus is vesicular with scattered chromatin giving a diffuse appearance to the nucleus all nuclei in the individual organism appear alike. Most protozoa can regenerate their lost parts as normally displayed at fission or encystment. All protozoans are eukaryotes and therefore possess a true or membrane-bound nucleus.
What does compact mean when describing the nucleus of protozoans. Protista may be either autotrophic or heterotrophic. As in all eukaryotes the nucleus is enclosed in a membrane.

Parasitic protozoa usually have slight regenerative capacity. Protista are single-celled organisms that have a true nucleus eukaryotic. Relative quantities of nuclear and cytoplasmic materials and size of the broken piece affect the rate and result of the process of regeneration.
It remains the case that most eukaryotic cells have a single nucleus and this includes all cell types that have been described during the life cycle of many protozoan parasites such as Trypanosoma and Leishmania. All protozoans as eukaryotes have nucleus. Protists have a nucleus because the taxonomic kingdom Protista refers to only those single-celled microorganisms who can neither be classified as belonging to the plant animal nor fungi kingdoms.
Though they do not have a nucleus prokaryotic cells still store their genes on chromosomes and still regulate their DNA. Protozoans have evolved to live under a great range of environmental conditions. Protozoan organism usually single-celled and heterotrophic using organic carbon as a source of energy belonging to any of the major lineages of protists and like most protists typically microscopic.
Protozoa are unicellular eukaryotes. Protozoa are Eukaryotic and unicellular organisms because they possess nucleus while prokaryotes are organisms which lack a nucleus.
