The kingdom Protista contains the single-celled eukaryotes in contrast to the bacteria which are examples of the prokaryotic cell type. Protists are a diverse group of organisms that are either unicellular or multicellular without highly specialized tissues.

Jun 22, 2020 · All living organisms can be categorized into 3 domains of life: Eukaryotes; Prokaryotes; Archaea; DOMAINS: “Domains” are the top-level classification which categorizes life in the most general way. For example, it separates the presence of a nucleus. Prokaryotes like archaea and bacteria don’t have one. But eukarya have a nucleus. Mushrooms Molds Yeast Protista Eukaryotic and generally unicellular Some protists are animal-like Protozoa Amoeba Paramecium Euglena Some protists are plant-like Algae Some protists are fungus-like Slime molds Porifera Phylum in the kingdom Animalia Sponges Sessile adult form, but motile larvae Filter feeders Don’t have digestive, nervous, or circulatory systems Cnidaria Phylum in the kingdom Animalia Jellyfish, anemones and corals Some are motile and others are primarily sessile. heterocyst Lab exercise-observe slide Kingdom: Protists Protists are not one distinct group but instead represent all the eukaryotes that are not plants, animals, or fungi. Protists differ from prokaryotes because they are eukaryotes that have a nucleus and contain DNA in chromosomes Protists are divided into three groups based on physical ...
Prokaryote Prokaryote Prokaryote Eukaryote Autotroph or Heterotroph Heterotoph VARIES VARIES – PLANTS and PROTISTS (algae) are the only AUTOTROPHS Stationary or Mobile Mobile Mobile Varies - PLANTS and FUNGI are Stationary PROTISTS and ANIMALS are mobile 1. Which two Domains contain organisms that do not have a nucleus in their cells? 8 hours ago · Short Answer – Answer each question in the space provided. Microorganisms include bacteria, fungi, archaea, protists and viruses, and are among the earliest known life forms. We always use the short answer, not only Yes or No. This is based on the five different kingdoms that all organisms are classified into. Plants have cells but animals do ... Nov 30, 2019 · Kingdom Protista Kingdom Protista: Protists are simple eukaryotic organisms that are neither animals, plants nor fungi. Protists are unicellular in nature, or they can be found as a colony of cells. Most protists live in water,... The other domain of the prokaryotes is composed of the organisms called archaebacteria, which are ancient life forms which may live in extreme environments. The genetic information of prokaryotes (their DNA) is typically in nucleoid of DNA strands, but they may have additional DNA in a circular loop called a plasmid. The eukaryotic cells occur in all eukaryotes votes like protists, plants, fungi and animals. For example, prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus. Prokaryotic cells lack internal cellular bodies (organelles), while eukaryotic cells possess them. Examples of prokaryotes are bacteria and archaea. Examples of eukaryotes are protists, fungi, plants, and animals (everything except prokaryotes). It includes unicellular prokaryotic organism e.g. Bacteria and Cyanobacteria. Kingdom Protoctista ( Protista ): It includes all unicellular, eukaryotic organisms, which are no longer classified as animals, Plants, or Fungi e.g. Euglena, Paramecium, Chlamydomonas Plasmodium . Cellular life has evolved along three major lineages, two of which are composed only of prokaryotic cells (Bacteria and Archaea); the third constitutes the eukaryotic lineage (Eukarya); called domains as the highest biological taxon. Plants, animals, fungi, and protists are all kingdoms within the domain Eukarya The universal tree of life:
Some fungi are saprobes (saprophytes), as important in decomposition as the bacteria; others are symbiotrophs, living in symbiotic association with plants, animals, protists, and cyanobacteria. Well-known symbioses are: lichens that are associations of fungi and green algae or cyanobacteria; mycorrhizae , associations of fungi and plant roots ... Prokaryotes (Archaea and Bacteria) reproduce asexually through binary fission, in which the parent organism divides in two to produce two genetically identical daughter organisms. Eukaryotes (such as protists and unicellular fungi ) may reproduce in a functionally similar manner by mitosis ; most of these are also capable of sexual reproduction.

The monerans are referred to as prokaryotes since they lack a true nucleus. All other groups of living organisms are known as eukaryotes. Later, taxonomists acknowledged that mushrooms and moulds are sufficiently different from plants and thus were placed in a separate kingdom called Fungi. Archaea; Bacteria; Eukarya; Domain Archaea; single-celled, "ancient" bacteria; Domain Bacteria; single-celled, "true" bacteria; Domain Eukarya; single-celled protists, paramecia, single- and multi-cellular algae; fungi; plants; animals . All organisms are grouped into a few major categories; earliest classification systems recognized 2 kingdoms ... Protists are a very diverse group of mostly single-celled organisms that are eukaryotes—that is, they have a true nucleus and organelles—and are not considered to belong to the animal, plant, or fungi kingdoms. They may live as solitary individuals or in groups called colonies, and they may be autotrophic or heterotrophic. In today’s lab you will examine specimens from three kingdoms: Eubacteria, Protista, and Fungi. Eubacteria and Protists are essentially unicellular organisms, although each kingdom includes some species that form colonies, or aggregations of individuals. Fungi are truly multicellular organisms. The eukaryotic cells are larger and more complex, composing the cells of animals, plants, and fungi in addition to the protists (algae, amoebae, and others). It was simply assumed that all cells which were not eukaryotes were similar and should be grouped together as prokaryotes. Higher cells with membranes and complexity The living world is divided into two classes of organism Eukaryotic and, much simpler, prokaryotic organisms such as bacteria Generally eukaryotes are diploid and their cells have internal organelles, such as nuclei Prokaryotes are haploid with much simpler cells
