Compare And Contrast Prokaryotes And Eukaryotic Cells

The nucleolus is one of the most important organelles. This organelle is a eukaryotic cell. The nucleolus is not like most of the other organelles. Most other organelles have a static structure but the nucleolus does not. The structural components are chains of RNA and DNA. It contains granular and fibrillar components.

Prokaryotic cells do not have a nucleus. The chromosomes which are found in prokaryotes are usually spread in the cytoplasm. In eukaryotic cells the chromosomes remain together inside the nucleus and there is a clear nuclear membrane that is surrounding the nucleus.

The Nucleolus is the organelle structure inside the nucleus; it supports the synthesis of ribosomes, which is where the Ribosomal RNA is produced. Some cells

Eukaryotes and bacteria cells both have the common cell structure of flagella. Flagella is considered a protein. The purpose of the flagella is to help the cell move. Eukaryotes have a different movement type than bacteria. Eukaryotes move in form of an s-shape. Bacterial cells move like helicopter blades (rotor type movement). The flagellum of the bacterial cell are a lot thinner the eukaryote due to the size of the cell.

Although both of these cells contain DNA, only eukaryotic cells contain a nucleus. The nucleus is the largest organelle, surrounded by a double membrane (nuclear envelope) containing lots of pores. The nuclear membrane protects contents of the nucleus and controls the transport of substances in and out. The nucleus contains linear DNA in chromatin which protects the DNA from damage. Chromatin is formed of DNA which controls the activities of the cell. The nucleus often contains a structure called the nucleolus. This structure produces ribosomes which enter the cytoplasm in the cell through the nuclear pores, as well as transcribing DNA into RNA.

One factor that every living thing has in common is that they are all composed of cells, the smallest structural and functional units of all organisms. Approximately two hundred different kinds exist, but the human body contains trillions. In all cells, there is a sheetlike boundary called a membrane that protects thousands of proteins, chromosomal DNA, called genetics, and other chemicals. Among cells are two distinct types with separately organized structures called prokaryotics and eukaryotics A nucleus, which carries genetics and determines the idenitity and function of a cell, exists in eukaryotes, along with many other organelles. Organelles are specially organized formations that allow cells to work properly. On the other hand, prokaryotes

Eukaryotes have an enclosed nucleus with paired DNA. Intracellular structures in prokaryotes have plasma membrane and lacks sterols. Eukaryotes have sterols with plasma membrane. Both have a cell membrane. Prokaryotes have a cell wall.

It is evidently known that the cell is the basic unit of life. Cells are microscopic, membrane-bound units which contain biomolecules allowing them to carry out functions, sustain life and self-replicate. Although every living cell comes under one of the 6 kingdoms in the biological taxonomy of living organisms, the two most distinct types of cells are eukaryotic cells and prokaryotic cells. Prokaryotes (pre-nucleus) are single-celled organisms which do not contain a nucleus nor do they have any membrane-bound organelles within them. Eukaryotes (literally meaning “true nucleus”) were developed many years after prokaryotes and can either be single-celled or multi-cellular organisms.

There are internal compartments and features within the cytoplasm of the eukaryotic cell. Membrane-enclosed organelles perform specific tasks within the cell. As noted earlier, enclosed in the nucleus is the DNA. The endoplasmic reticulum is a network of tubes and flattened sacs that is connected to the nuclear envelop. Also located within the eukaryotic cell is the Golgi apparatus. The Golgi apparatus has the appearance of flattened membrane sacs that are stacked together (Singh-Cundy, A., & Shin, G., 2015). In animal cells, lysosomes exist within the cytoplasm. In plant cells, a large vacuole exists. The mitochondria is pod-shaped, and located within the cytoplasm. Chloroplasts are green pods which are also located within the

Eukaryotic organisms have cells that contain a nucleus. Animals, plants, fungi, and protoctista all have eukaryotic cells. The eukaryotic cell has a plasma membrane as its external boundary like all other cells, but it also has a variety of membranes that divide the internal space into discrete compartments, which give them its unique feature, that enable the cell to carry out various chemical reactions or processes in separate parts of the cell, which all form part of the same system. The compartments in the cytoplasm are known as organelles.

If you examine Prokaryotes and Eukaryotes side by side, you will spot a number of disparities. To begin with, Prokaryotic cells are a lot smaller than Eukaryotic cells and have a simpler structure. However, this simple structure is actually an advantage for their lifestyle because it allows them to reproduce quickly

There are only two types of cell in the world, these are eukaryotic and prokaryotic cells. They are both similar and different in many ways, for example prokaryotes are only a few micrometres in size whereas eukaryotes are between 5-100 micrometres and nearly 10,000 times the volume of that of a prokaryote. A chemical similarity between the two is that they both either contain or use proteins, carbohydrates, lipids and nucleic acids to store or create energy. Both eukaryotes and prokaryotes are able to be divided into further subcategories, eukaryotes can be either animal or plant cells, and prokaryotes can be classified based on the composition of their cell wall, for example bacteria. In this essay I will also go on to talk about why prokaryotic cells still exist in the microscopic world even though eukaryotes are so much more advanced.

DNA occupies most of the remaining space inside a nucleus. DNA is inborn material that has the direction or the command to build proteins. Proteins are helping with most activity in the cells. Our DNA is arranged or structured in a systemic way into about 20,500 genes, basically instruction manuals for our bodies. Without all of these genes, our body would not be able to make proteins. Proteins are very necessary to make sure that everything in your body is working properly. The nucleus helps the cell to protect the very important DNA. More importantly, the nuclear envelope keeps your genes separate from the other things inside the cells. The things that make a eukaryotic cell are a defined nucleus. The nuclear envelope surrounded the nucleus and all of its materials. The nuclear envelope is like a membrane similar to the cell membrane around the cell. There are pores and spaces for RNA and proteins to pass through while the nuclear envelope keeps all of the chromatin and nucleolus

On examination of the prokaryotic cell, the internal structure is simple. Prokaryotic cells lack a nucleus. In fact, the name of the cell give a clue about the structure. In Greek term prokaryote, “pro” means before and “kary” is nucleus;

The definition of a ‘prokaryote’ is simply a single-celled organism with no nuclear membrane and consequently no membrane-bound organelles. It is therefore logical to assume that one would find a nucleus and membrane-bound organelles in a eukaryotic cell. Although the expression is widely accepted by myriad biologists and microbiologists alike and has been since the ‘birth’ of the term, the word has come under much scrutiny due to its ‘negative’ definition; as in ‘prokaryote’ describes that the cell is lacking characteristic eukaryotic features rather than being defined in its own terms (Woese, 1994; Pace, 2006).
