Which of the Following Are Considered Animal-like Protists
Protists are a diverse group of eukaryotic organisms belonging to Kingdom Protista. There are few similarities between individual members of this Kingdom, as it includes all the eukaryotes that are not animals, plants, or fungi.
Near 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 observe in their surrounding environment; others are photosynthetic and make their ain nutrient using chloroplasts.
Classification of Protists
Protists are always eukaryotic, and all protists contain a nucleus and other membrane-bound organelles. They are typically unicellular organisms, though a few are multicellular. Protists alive in aquatic environments and may be establish in freshwater, saltwater, or clammy soil habitats.
Besides these features, the members of Kingdom Protista have lilliputian in mutual with one some other. Protists come in a broad variety of different forms and may be classified as animal-similar, plant-like, or fungus-like, depending on their characteristics.
Animal-similar Protists
Animal-like protists are called protozoa (significant 'first animal'). All protozoans are unicellular and heterotrophic, significant they seek out food in their surrounding environments. Some animal-like protists prey on other, smaller microorganisms, which they engulf and digest in a process known equally phagocytosis. Others may feed on non-living, organic matter.Many protozoa take a mouthlike structure through which they tin ingest food particles, while some absorb nutrients through their cell membrane.
Protozoa typically have digestive vacuoles but, unlike other types of protists, they don't incorporate chloroplasts. Animal-like protists likewise lack a cell wall.
Examples of Animal-similar Protists
In that location are 4 main types of creature-like protists; these are the amoeba, the flagellates, the ciliates, and the sporozoans.
Amoeboid Protozoans
Amoeba are characterized past the presence of pseudopodia, or 'false anxiety,' which they apply to catch leaner and smaller protists.
Flagellated Protozoans
Flagellates have flagella, whip, or tail-like structures which they use to propel themselves through water. Some flagellates are parasitic, while others are complimentary-living.
Ciliated Protozoans
Ciliates are covered in cilia, tiny pilus-similar structures which they use to move around and waft food into their mouths.
Sporozoans
Sporozoans are parasitic organisms. One famous case is Plasmodium, the parasite known to cause malaria.
Fungus-like Protists
Fungus-similar protists are known as molds. Like truthful fungi, they are heterotrophic feeders and absorb nutrients from decaying organic affair in their environs. They also reproduce using spores. However, they differ from truthful fungi in that their cell walls incorporate cellulose, rather than chitin.
Examples of Fungus-similar Protists
The two major types of fungi-like protists are slime molds and h2o molds.
Slime Molds
Slime molds are often found on rotting logs, where they feed on decomposable organic matter. These molds are frequently unicellular but, when food is scarce, can swarm together to form a slimy mass. These brightly colored blobs can move very slowly in their search for food and, in some cases, tin can fuse to grade i enormous, multinucleated cell.
Water Molds
Water molds usually live on the surface of h2o, or in damp soil and, like slime molds, feed on decaying organic matter. This grouping contains several plant pathogens, including the devastating white potato disease known equally potato bane.
Institute-like Protists
Institute-like protists (AKA algae ) are usually photosynthetic organisms, and most contain chloroplasts and/or chlorophyll. Algal cells unremarkably have a cell wall which, like the prison cell walls of true plants, contain cellulose. However, different true plants, algae lack leaves, stems, and roots. Plant-like protists may reproduce asexually or sexually.
Most algal species are unicellular, though some form big, multicellular structures (for example, seaweeds ). Plant-like protists alive in aquatic environments and most species are constitute in oceans, lakes, and ponds.
Examples of Plant-like Protists
The 7 major groups of algae are blood-red algae, greenish algae, chocolate-brown algae, burn algae, gold-dark-brown algae, yellow-greenish algae, and euglenids.
Cerise Algae
Blood-red algae are typically establish 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 diversity of seaweeds.
Green Algae
Dark-green algae are the most abundant group of algae. They incorporate chloroplasts and cell walls and are idea to be the evolutionary ancestors of land plants. Light-green algae may exist unicellular or multicellular.
Brown Algae
Chocolate-brown algae are typically found in marine environments. They are multicellular organisms and grade a variety of plant-like species. The largest known case of brown algae is the behemothic kelp, which often grows to over 30m in length.
Fire Algae
Fire algae include a group of unicellular organisms chosen the dinoflagellates. Some dinoflagellates are bioluminescent and tin light up the surface of the ocean with an eerie, nighttime-time glow. When present in big numbers, dinoflagellates can besides cause a miracle known as 'cherry-red tide.'
Gold-dark-brown Algae and Diatoms
Golden-brown algae tin can be constitute in both marine and freshwater environments. This group includes the diatoms, photosynthetic organisms with transparent jail cell walls made of silica. Many species of marine plankton are diatoms.
Yellow-green Algae
Yellow-green algae are photosynthetic organisms that live predominantly in freshwater environments. Many take a jail cell wall that does not comprise cellulose (as in plants and algae) or chitin (like fungi and molds). The cell wall composition of yellow-green algae ismost completely unknown.
Euglenids
Euglena are photosynthetic algae that are found in a diversity of aquatic habitats. Euglenids typically have ane or more than flagella but lack a cell wall, and are instead encased by a protein-rich structure chosen a pellicle.
