Which Describes A Characteristic Shared By Plant-like, Animal-like, And Fungus-like Protists?
Protists are a diverse group of eukaryotic organisms belonging to Kingdom Protista. There are few similarities betwixt individual members of this Kingdom, as information technology includes all the eukaryotes that are not animals, plants, or fungi.
Most protists are microscopic and unicellular, though a few species are multicellular. Typically, protists reproduce asexually, though some are capable of sexual reproduction. Some protists are heterotrophs, and feed on other microscopic organisms and carbon-rich materials they find in their surrounding surround; others are photosynthetic and make their own food using chloroplasts.
Classification of Protists
Protists are e'er eukaryotic, and all protists contain a nucleus and other membrane-bound organelles. They are typically unicellular organisms, though a few are multicellular. Protists live in aquatic environments and may be found in freshwater, saltwater, or damp soil habitats.
Also these features, the members of Kingdom Protista take little in mutual with 1 another. Protists come up in a wide variety of dissimilar forms and may be classified every bit beast-similar, plant-like, or fungus-like, depending on their characteristics.
Brute-like Protists
Animal-similar protists are called protozoa (meaning 'commencement animal'). All protozoans are unicellular and heterotrophic, meaning they seek out food in their surrounding environments. Some fauna-like protists prey on other, smaller microorganisms, which they engulf and digest in a process known as phagocytosis. Others may feed on non-living, organic matter. Many protozoa have a mouthlike structure through which they can ingest food particles, while some absorb nutrients through their jail cell membrane.
Protozoa typically accept digestive vacuoles simply, unlike other types of protists, they don't contain chloroplasts. Animal-like protists also lack a cell wall.
Examples of Animal-like Protists
In that location are four primary types of animal-similar protists; these are the amoeba, the flagellates, the ciliates, and the sporozoans.
Amoeboid Protozoans
Amoeba are characterized by the presence of pseudopodia, or 'false anxiety,' which they utilise to catch bacteria and smaller protists.
Flagellated Protozoans
Flagellates take flagella, whip, or tail-similar structures which they employ to propel themselves through h2o. Some flagellates are parasitic, while others are costless-living.
Ciliated Protozoans
Ciliates are covered in cilia, tiny hair-similar structures which they use to motion around and waft food into their mouths.
Sporozoans
Sporozoans are parasitic organisms. I famous example is Plasmodium, the parasite known to cause malaria.
Fungus-like Protists
Mucus-like protists are known equally molds. Like true fungi, they are heterotrophic feeders and blot nutrients from decaying organic matter in their surroundings. They as well reproduce using spores. However, they differ from true fungi in that their prison cell walls contain cellulose, rather than chitin.
Examples of Fungus-like Protists
The two major types of fungi-like protists are slime molds and water molds.
Slime Molds
Slime molds are often found on rotting logs, where they feed on decomposable organic matter. These molds are often unicellular just, when food is scarce, tin swarm together to form a slimy mass. These brightly colored blobs tin can move very slowly in their search for food and, in some cases, can fuse to course one enormous, multinucleated cell.
H2o Molds
Water molds usually alive on the surface of h2o, or in clammy soil and, like slime molds, feed on decaying organic matter. This group contains several plant pathogens, including the devastating irish potato disease known as white potato blight.
Constitute-similar Protists
Institute-similar protists (AKA algae ) are usually photosynthetic organisms, and most contain chloroplasts and/or chlorophyll. Algal cells usually have a jail cell wall which, like the cell walls of true plants, incorporate cellulose. However, unlike true plants, algae lack leaves, stems, and roots. Institute-like protists may reproduce asexually or sexually.
Nearly algal species are unicellular, though some form large, multicellular structures (for instance, seaweeds ). Establish-similar protists live in aquatic environments and about species are found in oceans, lakes, and ponds.
Examples of Plant-like Protists
The 7 major groups of algae are red algae, greenish algae, brown algae, burn down algae, golden-brown algae, xanthous-green algae, and euglenids.
Red Algae
Ruddy algae are typically found in tropical marine environments where they often abound on flat surfaces, such as reefs. Though red algae may be unicellular, they are typically multicellular organisms and form a variety of seaweeds.
Green Algae
Greenish algae are the virtually abundant group of algae. They contain chloroplasts and cell walls and are thought to be the evolutionary ancestors of land plants. Green algae may exist unicellular or multicellular.
Brown Algae
Brown algae are typically found in marine environments. They are multicellular organisms and course a variety of plant-like species. The largest known example of chocolate-brown algae is the giant kelp, which oft grows to over 30m in length.
Burn Algae
Burn down algae include a group of unicellular organisms chosen the dinoflagellates. Some dinoflagellates are bioluminescent and can light up the surface of the ocean with an eerie, night-time glow. When present in big numbers, dinoflagellates can also cause a phenomenon known as 'red tide.'
Golden-brown Algae and Diatoms
Gilded-brown algae tin exist found in both marine and freshwater environments. This group includes the diatoms, photosynthetic organisms with transparent cell walls made of silica. Many species of marine plankton are diatoms.
Xanthous-green Algae
Yellow-green algae are photosynthetic organisms that live predominantly in freshwater environments. Many accept a jail cell wall that does non incorporate cellulose (as in plants and algae) or chitin (similar fungi and molds). The cell wall composition of yellow-green algae is nigh completely unknown.
Euglenids
Euglena are photosynthetic algae that are found in a variety of aquatic habitats. Euglenids typically have ane or more flagella but lack a cell wall, and are instead encased by a protein-rich structure chosen a pellicle.
