Prokaryotic organisms have existed for billions of years. These prokaryotic cells have gone through enough environmental changes to learn how to adapt quickly. As small organisms that reproduce rapidly, bacteria cells are the most abundant organisms on earth and the most important. Gram staining is used by scientists to help identify and classify bacteria due to the fact that it is difficult to discern unstained bacteria through light microscopes (1). Since bacteria are small organisms that are hard to distinguish through microscopes, the staining allows for the determination of shape (2). The staining is affected by the composure of the cell wall and how it can retain the dyes (4). The staining not allows for many characteristics to become

The typical organelle that prokaryotic cells use for movement is the flagella. The flagella is a tail of sorts that connects and projects out of the cell wall and propels the cell forward (6). On the outside surface of a bacterial cell, it is likely to find appendages that resemble thread strands (6). These thread like strands are called pilli and they enable the bacterial cell to move across surfaces (6). Bacteria cells also have the ability to move on impulse (6). These impulsive movement is known as taxis and it's the capacity for bacterial cells to be drawn towards or away from certain stimuli (3). Another form of locomotion is a collective type of motion. Bacteria cells will move towards each other and become a cluster of organized movement …show more content…
However, prokaryotic cells are categorized into two domains: archaea and bacteria. One of the main difference between archaebacteria and eubacteria prokaryotes is that archaebacteria is ancient. Due to the ancientness of archaebacteria, they can survive in extreme environments where most organisms cannot (9). The prokaryotes in these two domains also differ in the structure of their cell wall. Prokaryotes that contain peptidoglycan in their cell wall belong in the domain bacteria while prokaryotes in archaea do not contain peptidoglycan (9). Archaebacteria membranes differ in their lipid structure being constructed of branched hydrocarbon chains instead of unbranched fatty acid chains (10). The flagella in both domains appears similar but was evolved differently for both domains (9). Although the prokaryotes in both domains reproduce asexually through binary fission, eubacteria, however, can remain dormant for years by producing spores (9). The rRNA in archaebacteria is unique to it (10). The last difference between these two domains is that archaebacteria is more affected by antibiotics used for eukarya than bacteria
