archaea prokaryotic or eukaryotic
Prokaryotic cells comprise bacteria and archaea. In the earlier systems of classifications Archaea were treated as a unique type of bacteria called Archaebacteria and they were included in the Kingdom Monera along with true bacteria and Cyanobacteria blue green algae.

Introduction from Wikipedia The Archaea constitute a domain or kingdom of single-celled microorganisms.
. Links to the more detailed articles on each of the major groups are provided. Find more free tutorials videos and readings for th. Eubacteria Bacteria and 3. Now we are certain that Archaea possess distinct.
Prokaryotes are made up of a. The major groups of microorganismsnamely bacteria archaea fungi yeasts and molds algae protozoa and virusesare summarized below. Prokaryotic cells such as bacteria and archaeans do not have a membrane-bound nucleus. What are prokaryotic and eukaryotic cells.
Like a prokaryotic cell a eukaryotic cell has a plasma membrane cytoplasm and ribosomes but a eukaryotic cell is typically larger than a prokaryotic cell has a true nucleus meaning its DNA is surrounded by a membrane and has other membrane-bound organelles that allow for compartmentalization of functions. Their genetic material isnt stored within a membrane-bound nucleus. In these cells the cytoplasm consists of all of the contents of the cell inside the plasma membrane. Genome refers to the entire collection of DNA of an organism.
In eukaryotic cells such as plant and animal cells the cytoplasm consists of three main components. The key difference between prokaryotic and eukaryotic genome is that the prokaryotic genome is present in the cytoplasm while eukaryotic genome confines within the nucleus. Hence the evolutionary history and biology of archaea increasingly comes to bear on eukaryotic origins more than ever before. Prokaryotic cells are normally smaller than eukaryotic cells with a typical size range of 01 to 5 μm in diameter.
CLEAR AND SIMPLE- Understand the similarities and differences between prokaryotic and eukaryotic cells. Eukaryotic cells tend to be 10 to 100 times the size of. Microbiology came into being largely through studies of bacteria. In other words the genome is the genetic material of an organism that contains the total genetic information.
Bacteria constitute a large domain of prokaryotic microorganisms. Bacteria Archaea and Eukarya. All living things can be divided into three basic domains. They are the cytosol organelles and various particles and granules called.
Instead it is stored in a nucleoid that floats in the cells cytoplasm. Here we have compiled a survey of endosymbiotic theories for the origin of eukaryotes and mitochondria and for the origin of the eukaryotic nucleus summarizing the essentials of each and contrasting some of their predictions to the. The experiments of Louis Pasteur in France Robert Koch in Germany and others in the late 1800s. These microbes are prokaryotes meaning that they have no cell nucleus or any other membrane-bound organelles in their cells.
