What are the 3 main groups of Kingdom Protista?
Protists are a diverse kingdom, including all eukaryotic organisms that are neither animals, nor plants, nor fungi. For classification, the protists are divided into three groups: animal-like protists, plant-like protists, and fungi-like protists.
What is the protists Kingdom?
Protists are organisms that are part of the biological kingdom called the protista. These organisms are not plants, animals, bacteria, or fungi. Protists are a very diverse group of organisms. They are basically all the organisms that don’t fit into the other groups.
What 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.
What do protists eat?
Protists Nutrition 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.
Do protists cause disease?
Most protist diseases in humans are caused by protozoa. Protozoa make humans sick when they become human parasites. Trypanosoma protozoa cause Chagas disease and sleeping sickness. Giardia protozoa cause giardiasis, and Plasmodium protozoa cause malaria.
What are bad protists?
Bad protists. Pathogens – animal-like protists cause malaria, African sleeping sickness, amebic dysentery and Giardia. Parasites. Can cause plant diseases. Water mold was a cause of the Irish potato famine in the 1800s.
What are the benefits of protists?
Protists produce almost one-half of the oxygen on the planet through photosynthesis, decompose and recycle nutrients that humans need to live, and make up a huge part of the food chain. Humans use protists for many other reasons: Many protists are also commonly used in medical research.
How are protists treated?
Amoxicillin, penicillin, and erythromycin are common antibiotics that inhibit bacterial cell functions. Antibiotics are derived primarily from bacteria or fungi (mold), such as Penicillium. Antibiotics don’t work exclusively against bacteria: some ‘broad-spectrum’ ones are also effective against protists.
How are protists prevented?
People sleep under mosquito nets and wear insect repellent to avoid bites. Antimalarial drugs are also taken, which treat the symptoms and can prevent infection.
What do viruses and protists have in common?
Prokaryotes and Protists both replicate without invasion, so they can spread quickly and efficiently. They are also simple structures, with the Protists being the most complex — protists have a full protein nucleus — and the Virus the most simple — viruses are just a protein strand with instructions to replicate.
Are viruses protists?
Protists are unicellular eukaryotes and harbor a wide spectrum of viruses, from small RNA viruses to giant DNA viruses.
