What Are Protist


What is a protist in biology?

Protists are a diverse collection of organisms. While exceptions exist, they are primarily microscopic and unicellular, or made up of a single cell. The cells of protists are highly organized with a nucleus and specialized cellular machinery called organelles. via

What are protists short answer?

The protist kingdom includes protozoa and algae. Unicellular protozoa and algae are unicellular eukaryotes. Pluricellular algae are also eukaryotes of simple structure. Protists are believed to be the phylogenetic ancestors of the living organisms of the other eukaryotic kingdoms (fungi, animals and plants). via

What are 5 characteristics of protists?

Characteristics of Protists

  • They are eukaryotic, which means they have a nucleus.
  • Most have mitochondria.
  • They can be parasites.
  • They all prefer aquatic or moist environments.
  • via

    How would you describe protists?

    Protists are eukaryotic organisms that cannot be classified as a plant, animal, or fungus. They are mostly unicellular, but some, like algae, are multicellular. Protists primarily live in water, though some live in moist soil. They can be found almost anywhere on Earth where there is liquid water, even in humans. via

    What are 2 examples of protists?

    Examples of protists include: amoebas (including nucleariids and Foraminifera); choanaflagellates; ciliates; diatoms; dinoflagellates; Giardia; Plasmodium (which causes malaria); oomycetes (including Phytophthora, the proximate cause of the Great Famine of Ireland); and slime molds. via

    What do protists look like?

    The cells of protists are among the most elaborate of all cells. Most protists are microscopic and unicellular, but some true multicellular forms exist. Still other protists are composed of enormous, multinucleate, single cells that look like amorphous blobs of slime, or in other cases, like ferns. via

    What do protists eat?

    That means that protists can obtain food like plants, fungi, or animals do. There are many plant-like protists, such as algae, that get their energy from sunlight through photosynthesis. Some of the fungus-like protists, such as the slime molds (Figure below), decompose decaying matter. via

    Is protista a kingdom?

    Protists are a group of all the eukaryotes that are not fungi, animals, or plants. As a result, it is a very diverse group of organisms. The eukaryotes that make up this kingdom, Kingdom Protista, do not have much in common besides a relatively simple organization. via

    Is a protist a bacteria?

    The primary difference between them is their cellular organization. Bacteria are single-celled microbes and are prokaryotes, which means they're single-celled organisms lacking specialized organelles. In contrast, protists are mostly single-celled eukaryotic organisms that are not plants, fungi, or animals. via

    Which best describes the offspring of protists?

    Asexual binary fission in protists is one major mechanism of reproduction. A single-celled protist's body is separated into two parts, or halves. After this process, there is no longer a "parental" body, but a pair of offspring. These offspring are called daughter nuclei. via

    What are 3 characteristics of plant-like protists?

    Characteristic of plant-like protists

  • Eukaryotic organism.
  • There are unicellular (form of yarn / ribbon) and some are multicellular (sheet form).
  • Has chlorophyll, so it is autotrophic.
  • Algae / algae bodies are indistinguishable from roots, stems, and leaves.
  • via

    What are the four major types of protists?

    Major Groups of Protists

  • Chrysophytes. This group comprises of the diatoms and golden algae (desmids).
  • Dianoflagellates. These organisms are usually marine and photosynthetic.
  • Euglenoids. These are mostly freshwater organisms.
  • Slime Moulds. Slime moulds are saprophytic protists.
  • Protozoans.
  • via

    Where are protists found?

    Most protists can be found in moist and wet areas. They can also be found in tree trunks and other organisms. via

    How do you classify protists?

    The protists can be classified into one of three main categories, animal-like, plant-like, and fungus-like. Grouping into one of the three categories is based on an organism's mode of reproduction, method of nutrition, and motility. via

    What is the characteristics of Kingdom Protista?

    Protists have nuclear membranes around their DNA. They also have other membrane-bound organelles. Many protists live in aquatic habitats, and most are motile, or able to move. Protists have complex life cycles that may include both sexual and asexual reproduction. via
