Amoebae, slime mold, algae and protactists are some examples of unicellular organisms. Unicellular organisms fall under the main groups of bacteria, archaea, protozoa, single-celled algae and single-celled fungi. The two general categories are prokaryotes, which lack membrane-bound nuclei and membrane-bound organelles, such as mitochondria; and eukaryotes, which are more complex, having membrane-bound organelles and nuclei.Know More
Unicellular organisms are ubiquitous to most environments on Earth. Unicellular organisms have been found in the most extreme environments, such as arid deserts, frozen tundra, highly acidic subterranean environments and hydrothermal vents on the ocean floor; these organisms are called extremophiles. Extremophiles are described by the environments in which they grow optimally, such as acidophilic for acidic environments and thermophilic for environments with high temperatures.
Unicellular organisms can be innocuous to humans, but they are also responsible for diseases. Malaria is caused by a unicellular parasite of genus plasmodium. It is prevalent in tropical and sub-tropical environments. As of 2010, there were an estimated 219 million cases of malaria resulting in 660,000 deaths worldwide. The disease is transmitted from person to person by the bite of the Anopheles mosquito. Prevention includes the use of mosquito nets, pesticides and disruption of mosquito breeding grounds. There are several forms of treatment for malaria as well as ongoing development of a vaccine.Learn more about Biology
A short list of binomial nomenclature names includes Homo sapiens, Gorilla gorilla, Aloe polyphylla and Odocoileus virginianus. Homo sapiens is the name for human beings. It means "wise man." Homo sapiens is the only extant species of human on Earth.Full Answer >
A unicellular organism is any life form that is composed of a single cell; they live and carry out all life processes as a single cell. Based on their complexity, unicellular organisms can be placed in one of two categories: eukaryote and prokaryote. Most unicellular organisms are microscopic, but some are visible to the naked eye.Full Answer >
All organisms in the Kingdom Plantae are multicellular, which means that each organism is comprised of more than one cell. Being multicellular allows plants to grow large and complex, since the cells can differentiate and serve various different functions for the plant.Full Answer >
Unicellular organisms eat using a processes called phagocytosis. This process allows the single-celled organism to bring food into the inner part of the cell for digestion.Full Answer >
