What are some examples of prokaryotic cells?
Azotobacter vinelandii
What organelles are only found in prokaryotic cells?
Prokaryotic cells lack organelles found in eukaryoitic cells such as mitochondria, endoplasmic reticuli, and Golgi complexes. According to the Endosymbiotic Theory , eukaryotic organelles are thought to have evolved from prokaryotic cells living in endosymbiotic relationships with one another.
What type of organisms are prokaryotes?
– There are two basic types of organisms based on cell type: Prokaryotic and Eukaryotic. Prokaryotic cells are divided into the domains Bacteria and Archaea. – Prokaryotes are the smallest forms of life that can live independently. Most prokaryotes are tiny single cells, but some can form larger, multi-celled structures. – The most familiar prokaryotes are bacteria. Bacteria are a very diverse group that have several shapes, depending on the species. – Some prokaryotes, mainly in domain Archaea, can live in extreme environments. – Extreme thermophiles live in hot places such as volcanic springs and hydrothermal vents. – Extreme halophiles live in water of high saline content, and acidophiles thrive at very low pH. – Methanogens are poisoned by oxygen and live in places like swamps and the gut of animals. – Many biologists believe that if life exists elsewhere in our solar system, it will resemble thermophiles and methanogens; fossils of prokaryotes in meteorites have recently been reported. – Prokaryotes have been utilized as sources of enzymes that work under extreme conditions.
What are some examples of organisms that are prokaryotes and eukaryotes?
Examples of Prokaryotes Prokaryotes are all single-celled organisms, most of which you know of as bacteria. Single celled organisms like yeast, paramecia and amoebae are all eukaryotes. Grass, potatoes, and pine trees are all eukaryotes, as are algae, mushrooms, and tapeworms.
