Bacterial And Eukaryotic Cells Similarities

Eukaryotic cells and bacterial cells share some similarities, however, also contribute many differences due to the size difference between the two different cells. Due to the size difference between eukaryotic and bacterial cells, structural characteristics such as the presence of a nucleus, mitochondria, endomembrane system, cytoskeleton, membrane-bounded organelles, and number of chromosomes occur. All bacteria are one-celled organisms. There is no form of bacteria that contains a nucleus. However, this is not the case in eukaryotic cells. The eukaryotic cell’s most important component is the nucleus. This is a compartment that is surrounded by membranes that houses the DNA that is eventually divided into chromosomes. The nucleus protects

Actin is involved in many cellular processes that involve motion such as the division of animal cells that results in two daughter cells during sexual reproduction. Another example of actin being utilized by the cell is when amoeba or other similar eukaryotic cells crawl. While crawling, these cells are utilizing the rapid synthesis of actin filaments. Microtubules provide support and cell movement within a eukaryotic cell. They provide tracks for proteins that transport vesicles and other cellular material around the inside of the cell. Microtubules also play a role during cell division in sexual reproduction when they form a spindle and pull chromosomes apart. They are also one of the main structures in cell movement that involves cells that contain flagella and cilia. Lastly, intermediate filaments are responsible mainly for providing structural support to the eukaryotic cell. Intermediate filaments are able to provide resistance to tension, therefore have the ability to maintain the shape of the cell and keep essential organelles in place. They are more permanent structures in the cell due to their inability to depolymerize

This organelle is present in all eukaryotic cells and is used to create cell energy, known as adenosine triphosphate, or ATP. The creation of cellular energy through mitochondria is vital to the sustainability of the eukaryotic cell due to the large size and many processes that are being carried out throughout the cell. These processes require energy, therefore, a form of generating energy is necessary in order to keep the cell functioning properly and efficiently. The origins of this organelle can be explained through the theory of
