Both Animal-like and Fungus-like Protists Are
Protists are a diverse group of eukaryotic organisms belonging to Kingdom Protista. There are few similarities between individual members of this Kingdom, equally 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 environment; others are photosynthetic and make their own food using chloroplasts.
Classification of Protists
Protists are always eukaryotic, and all protists contain a nucleus and other membrane-jump 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.
Besides these features, the members of Kingdom Protista have fiddling in common with one another. Protists come in a wide multifariousness of different forms and may be classified every bit animal-like, plant-like, or fungus-like, depending on their characteristics.
Animate being-like Protists
Brute-similar protists are chosen protozoa (meaning 'first brute'). All protozoans are unicellular and heterotrophic, meaning they seek out food in their surrounding environments. Some animal-similar protists prey on other, smaller microorganisms, which they engulf and digest in a process known every bit phagocytosis. Others may feed on non-living, organic affair.Many protozoa take a mouthlike structure through which they can ingest food particles, while some absorb nutrients through their cell membrane.
Protozoa typically have digestive vacuoles merely, dissimilar other types of protists, they don't comprise chloroplasts. Beast-like protists also lack a prison cell wall.
Examples of Animate being-similar Protists
There are four main types of fauna-like protists; these are the amoeba, the flagellates, the ciliates, and the sporozoans.
Amoeboid Protozoans
Amoeba are characterized past the presence of pseudopodia, or 'faux anxiety,' which they use to grab bacteria and smaller protists.
Flagellated Protozoans
Flagellates take flagella, whip, or tail-like structures which they apply to propel themselves through water. Some flagellates are parasitic, while others are free-living.
Ciliated Protozoans
Ciliates are covered in cilia, tiny hair-like structures which they use to movement effectually and waft food into their mouths.
Sporozoans
Sporozoans are parasitic organisms. One famous example is Plasmodium, the parasite known to cause malaria.
Fungus-similar Protists
Fungus-similar protists are known as molds. Similar truthful fungi, they are heterotrophic feeders and absorb nutrients from decaying organic affair in their environment. They also reproduce using spores. However, they differ from true fungi in that their jail cell walls contain cellulose, rather than chitin.
Examples of Mucus-similar Protists
The two major types of fungi-like protists are slime molds and water molds.
Slime Molds
Slime molds are frequently found on rotting logs, where they feed on decomposable organic matter. These molds are often unicellular but, when food is scarce, tin can swarm together to grade a slimy mass. These brightly colored blobs can move very slowly in their search for food and, in some cases, tin fuse to form one enormous, multinucleated cell.
Water Molds
Water molds usually alive on the surface of water, or in damp soil and, like slime molds, feed on decaying organic matter. This grouping contains several plant pathogens, including the devastating potato illness known as spud blight.
Institute-like Protists
Plant-similar protists (AKA algae ) are commonly photosynthetic organisms, and nigh comprise chloroplasts and/or chlorophyll. Algal cells unremarkably take a cell wall which, like the cell walls of true plants, contain cellulose. However, unlike true plants, algae lack leaves, stems, and roots. Constitute-similar protists may reproduce asexually or sexually.
Most algal species are unicellular, though some course large, multicellular structures (for instance, seaweeds ). Plant-similar protists live in aquatic environments and most species are found in oceans, lakes, and ponds.
Examples of Plant-similar Protists
The 7 major groups of algae are ruby algae, green algae, brown algae, fire algae, golden-dark-brown algae, yellow-dark-green algae, and euglenids.
Cherry Algae
Red algae are typically found in tropical marine environments where they often grow on apartment surfaces, such as reefs. Though ruby algae may exist unicellular, they are typically multicellular organisms and form a variety of seaweeds.
Green Algae
Green algae are the most arable group of algae. They contain chloroplasts and prison cell walls and are thought to be the evolutionary ancestors of state plants. Greenish algae may be unicellular or multicellular.
Brown Algae
Brown algae are typically found in marine environments. They are multicellular organisms and grade a multifariousness of plant-like species. The largest known example of brown algae is the giant kelp, which frequently grows to over 30m in length.
Fire Algae
Burn algae include a group of unicellular organisms chosen the dinoflagellates. Some dinoflagellates are bioluminescent and tin light upwardly the surface of the bounding main with an eerie, night-time glow. When nowadays in large numbers, dinoflagellates can likewise cause a phenomenon known as 'cherry-red tide.'
Gold-brown Algae and Diatoms
Golden-brown algae can be institute 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.
Yellow-green Algae
Yellow-green algae are photosynthetic organisms that live predominantly in freshwater environments. Many have a jail cell wall that does not contain cellulose (every bit in plants and algae) or chitin (like fungi and molds). The cell wall composition of xanthous-dark-green algae isalmost completely unknown.
Euglenids
Euglena are photosynthetic algae that are found in a diverseness of aquatic habitats. Euglenids typically accept 1 or more flagella just lack a cell wall, and are instead encased by a protein-rich structure called a pellicle.
