Which of the following statements about protists is not true?
Answer: D. Their cells have no nucleus. Protists are most often single-celled eukaryotic organisms, which means that they have a nucleus and cellular organelles, and we can find them most often in the aquatic environment.
Answer and Explanation: The following statement is false: e) Photosynthetic protists are called protozoa. This is not true, because protozoa are animal-like protists that...
The statement that is true of the kingdom protists is that all are eukaryotic. Therefore, option D) All are eukaryotic is true. In general, protist is called eukaryotic organism which is not a plant, animal, or fungus. However, the protists also do not form any natural clade or a group.
Which of the following is true for all protists? Protists are eukaryotic organisms that are not plants, animals, or fungi.
Kingdom Protista is not considered a true kingdom because, this kingdom comprises many organisms, which are related to the kingdoms of fungi, plants and animals.
So the correct option is 'Eukaryotic organism'.
- Protists are usually aquatic, present in the soil or in areas with moisture.
- Protists are eukaryotic and have a membrane bound nucleus.
- Protists are eukaryotic organisms that cannot be classified as a plant, animal, or fungus.
A cell wall with a peptidoglycan is usually found in plants, fungi, bacteria, algae, and archaea. Therefore, it is not a characteristic of a protist. Some protists lack cell wall. However, for those that have one, their cell walls are made up of cellulose.
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.
Which of the following best describes protists? They are a diverse group of eukaryotes that includes several unrelated lineages.
What are the 4 main types of protist?
Protists include: (1) protozoa, the animal-like protists, (2) algae, the plant-like protists, and (3) slime molds and water molds, the fungus-like protists.
What are characteristics that all protist have in common? Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very little in common.
Protista. Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall. They have organelles including a nucleus and may have chloroplasts, so some will be green and others won't be.
What are some general characteristics of protists? Most are unicellular, but some are multicellular. Many are free-living, but some are parasitic. Many reproduce asexually, but not all.
Definition of protist
: any of a diverse taxonomic group and especially a kingdom (Protista synonym Protoctista) of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that typically include the protozoans, most algae, and often some fungi (such as slime molds)
Examples of protists include algae, amoebas, euglena, plasmodium, and slime molds.
protist definition. any organism that is not a plant, animal, fungus, or a prokaryote.
The unique characteristics of protists are: They have a membrane-enclosed nucleus. They include both unicellular organisms. They may be autotrophic or heterotrophic in nature.
Which of the following is incorrect about protozoan pathogens? Protozoa cannot be spread through body fluids. Please select the primary characteristics which are used to classify fungi.
The term 'Protista' is derived from the Greek word “protistos”, meaning “the very first“. These organisms are usually unicellular and the cell of these organisms contains a nucleus which is bound to the organelles. Some of them even possess structures that aid locomotion like flagella or cilia.
Which statement about algae is true?
So, the correct answer is 'Body of Algae is thallus'.
protist, any member of a group of diverse eukaryotic, predominantly unicellular microscopic organisms. They may share certain morphological and physiological characteristics with animals or plants or both.
Protists include: (1) protozoa, the animal-like protists, (2) algae, the plant-like protists, and (3) slime molds and water molds, the fungus-like protists.
The Protozoa is often divided into 4 phyla : Amoebalike protists, flagellates, ciliates, and spore-forming protists.
Algae are small plants that grow in water. They are found around taps and are slippery in nature. They spread during the rainy season. Thus, option D is incorrect.
Algae can be classified according to their pigments as red algae, brown algae and green algae. No zoospores or cells with flagella are produced by Spirogyra. All algae are not filamentous. Thus, the correct answer is option C.
The correct answer is Blue-Green Algae. Algae: Algae are chlorophyll-bearing, simple, thalloid, autotrophic, and largely aquatic (both fresh water and marine) organisms. They occur in a variety of other habitats: moist stones, soils, and wood.
A cell wall with a peptidoglycan is usually found in plants, fungi, bacteria, algae, and archaea. Therefore, it is not a characteristic of a protist. Some protists lack cell wall. However, for those that have one, their cell walls are made up of cellulose.
Protists are a diverse collection of organisms that do not fit into animal, plant, bacteria or fungi groups. While exceptions exist, they are primarily microscopic and made up of a single cell (unicellular), according to the educational website CK-12 (opens in new tab).
Answer and Explanation: Bacteria do not belong to kingdom Protista. Although bacteria are unicellular, as are most protists, they are very different organisms. Bacteria...
