Which Best Describes an Extreme Environment Where Archaebacteria Might Live

They are organisms that possess the ability to survive conditions that are too extreme or harsh for human existence and survival. Other organisms die in extremely salty conditions.

Microbiology Of Extreme Environments Types And Examples

Answers C and D are correct C.

. Prokaryotic cells do not have a cell nucleus while eukaryotic cells do. Vetriani et al 1999. The microorganism Sulfolobus acidocaldarius lives in extreme environments such as Emerald Hot Spring in Yellowstone National Park.

The point where the advent of the cell nucleus most likely happened is the branch point where Archaea split from Eukarya. They are found in hot springs salt lakes oceans soils and marshlands. If its super hot more than 100 Celsius freezing acidic alkaline salty deep in the ocean even bombarded by gamma or UV radiation theres probably life there and that life is probably archaeal species.

They include organisms from all the three main domains of microbial species namely Archaea Bacteria and Eukarya. Archeabacteria are singled cell microorganisms that live in extreme environment. Thermophiles halophiles and methanogens are the three types of archeabacteria.

Microbial ecosystems found in extreme environments like the Atacama Desert the Antarctic Dry Valleys and the Rio Tinto may be analogous to potential life forms adapted to Martian conditions. The first observed archaea were extremophiles living in extreme environments such as hot springs and salt lakes with no other organisms. Organisms in archaea have significant differences from bacteria in their genetic sequences Differences between Archaea and Bacteria The cellular structure of archaea is similar to that of bacteria.

Where do archaebacteria like to live. Some are even able to survive in temperatures above. Archaebacteria are able to survive in extreme conditions and therefore also known as extremophiles.

Archaea that live in extremely salty conditions are known as extreme halophiles lovers of salt. They are often called extremophiles. Another remarkable trait of archaebacteria is their ability to survive in extreme environments including very salty very acidic and very hot surroundings.

They can survive and even thrive under some of the most difficult conditions on planet Earth like very hot extremely acidic or very alkaline environments. The Domain Bacteria is made up of prokaryotes and likely originated 38 billion years ago. Until the 1970s this group of microbes was classified as bacteria.

Despite their extreme physical and chemical conditions they contain abundant forms of microbial life. Extreme halophiles are found in places such as the Dead Sea the Great Salt Lake and Lake Assal which have salt concentrations much higher than ocean water. Bacteria inhabit extreme environments and are not linked to human diseases.

Improved molecular detection tools led to the discovery of archaea in almost every habitat including soil oceans and marshlands. Archaea are a group of micro-organisms that. They can live in a variety of environments and are hence called extremophiles.

Only archaea are known to produce methane. Archaebacteria have been recorded surviving temperatures as high as 190 Fahrenheit which is only twenty-two degrees shy of the boiling point of water and acidities as high as 09 pH. They may be extremely abundant in.

The domain Archaea includes the majority of presently known extremophiles organisms that live at physical or chemical extremes. Archaebacteria are found in very harsh conditions such as in the volcanic vents or at the bottom of the sea. They can survive in conditions that are highly acidic alkaline saline aquatic environment.

This is the best answer because the domains Archaea and Bacteria on the tree of life are prokaryotic cells. While a majority these type of organisms are microbes a few higher organisms are also found to. They posses different shapes like rods spheres spiral and plates.

Halophilic archaea prefer a concentration of salt close to saturation and perform photosynthesis using bacteriorhodopsin. The Domains Bacteria and Archaea are genetically identical. They can withstand a very high pressure of more than 200 atmospheres.

Archaeans may be the only organisms that can live in extreme habitats such as thermal vents or hypersaline water. They can easily survive in such extreme environment as sea vents releasing sulfide-rich gases hot springs or boiling mud around volcanoes. Hydrothermal site Logatchev at 3000 m depth on the Atlantic Ridge.

Some archaea are extremophiles living in environments with extremely high or low temperatures or extreme salinity. Archaea are famous for their love of living in extreme environments. Archaeans are extreme organisms.

Some exist as single cells others form filaments or clusters. Rennett Stowe flickr Within harsh environments like hot springs volcanic craters and deep-sea hydrothermal vents uninhabitable by most life forms microscopic organisms are thriving. Similar to bacteria Archaeans have a number of different shapes.

An unusual flat square-shaped species that lives in salty pools has also been discovered. Cocci round bacilli rod-shaped and irregular are some examples. The Domain Eukarya is more closely related to the Domain Bacteria than to the Domain Archaea.

Methane-producing archaea are called methanogens. Archaea can be spherical rod spiral lobed rectangular or irregular in shape. Archaea increasingly are being discovered however in less extreme types of environments including the marine plankton lakes and sediments eg DeLong 1998.

Photography of different extreme environments. They can survive in acidic and alkaline aquatic regions and also in temperature above boiling point. Organisms in archaea live in extreme environments where bacteria cannot live D.

Thanks to them we have discovered environments that have long been considered incompatible with life.
