Learn About the Different Types of Cells Prokaryotic and Eukaryotic

The earth was formed about 4.6 billion years ago. For a very long period of the earths history, there was a very hostile and volcanic environment. It is difficult to imagine any life being viable in those types of conditions. It wasnt until the end of the Precambrian Era of the Geologic Time Scale when life began to form. There are several theories about how life first came to be on Earth. These theories include the formation of organic molecules within what is known as the Primordial Soup, life coming to Earth on asteroids (Panspermia Theory), or the first primitive cells forming in hydrothermal vents. Prokaryotic Cells The simplest type of cells were most likely the first type of cells that formed on Earth. These are called prokaryotic cells. All prokaryotic cells have a cell membrane surrounding the cell, cytoplasm where all of the metabolic processes happen, ribosomes that make proteins, and a circular DNA molecule called a nucleoid where the genetic information is held. The majority of prokaryotic cells also have a rigid cell wall that is used for protection. All prokaryotic organisms are unicellular, meaning the entire organism is only one cell. Prokaryotic organisms are asexual, meaning they do not need a partner to reproduce. Most reproduce through a process called binary fission where basically the cell just splits in half after copying its DNA. This means that without mutations within the DNA, offspring are identical to their parent. All organisms in the taxonomic domains Archaea and Bacteria are prokaryotic organisms. In fact, many of the species within the Archaea domain are found within hydrothermal vents. It is possible they were the first living organisms on Earth when life was first forming. Eukaryotic Cells The other, much more complex, type of cell is called the eukaryotic cell. Like prokaryotic cells, eukaryotic cells have cell membranes, cytoplasm, ribosomes, and DNA. However, there are many more organelles within eukaryotic cells. These include a nucleus to house the DNA, a nucleolus where ribosomes are made, rough endoplasmic reticulum for protein assembly, smooth endoplasmic reticulum for making lipids, Golgi apparatus for sorting and exporting proteins, mitochondria for creating energy, a cytoskeleton for structure and transporting information, and vesicles to move proteins around the cell. Some eukaryotic cells also have lysosomes or peroxisomes to digest waste, vacuoles for storing water or other things, chloroplasts for photosynthesis, and centrioles for splitting the cell during mitosis. Cell walls can also be found surrounding some types of eukaryotic cells. Most eukaryotic organisms are multicellular. This allows the eukaryotic cells within the organism to become specialized. Through a process called differentiation, these cells take on characteristics and jobs that can work with other types of cells to create an entire organism. There are a few unicellular eukaryotes as well. These sometimes have tiny hair-like projections called cilia to brush away debris and may also have a long thread-like tail called a flagellum for locomotion. The third taxonomic domain is called the Eukarya Domain. All eukaryotic organisms fall under this domain. This domain includes all animals, plants, protists, and fungi. Eukaryotes may use either asexual or sexual reproduction depending on the organisms complexity. Sexual reproduction allows more diversity in offspring by mixing the genes of the parents to form a new combination and hopefully a more favorable adaptation for the environment. The Evolution of Cells Since prokaryotic cells are simpler than eukaryotic cells, it is thought they came into existence first. The currently accepted theory of cell evolution is called the Endosymbiotic Theory. It asserts that some of the organelles, namely the mitochondria and chloroplast, were originally smaller prokaryotic cells engulfed by larger prokaryotic cells.

The French Revolution - 1575 Words

Just about any country that one can name has some history of civil unrest, class issues, rioting in the streets, and outright warfare. These patterns of behavior are common denominators for most civilization in the world. The names, faces, and places may change, but the motivations are generally the same, because of the need for change and the willingness to do whatever is necessary to achieve it. In contrast to the United States, which was in the process of freeing itself from British colonial rule, France was working to free itself from royal absolutism. This period is historically known as the French Revolution. Many scholars do not agree on the chronology of the French Revolution; some scholars suggest that the Revolution took place between 1789 to 1799 while others feel that it did not end until Napoleon lost power in 1815. To better understand the history of the French Revolution it is necessary to discuss the causes, major events, significant figures, and the outcomes associat ed with these political developments. Without this uprising, that changed the face of the entire country and influenced local political life in many countries in Europe, in all likelihood the France we know today would never have existed.

Conflict between Soft Skills &Technical Skills-Myassignmenthelp.com

Question: Discuss about the article Whose skill is it anyway? Soft skills and polarization written by Irena Grugulis and Steven Vincent (Grugulis and Vincent 2009). Answer: Introduction: The following report has concentrated on an article called Whose skill is it anyway? Soft skills and polarization written by Irena Grugulis and Steven Vincent (Grugulis and Vincent 2009). Different aspects of the article have been discussed in this report. Analysis: Focus: In the article Whose skill is it anyway? Soft skills and polarization, the writers have mainly concentrated on the skills that employers are looking for while recruiting employees in the organization. It has focused on the large business organization and analysed the recruitment process of the organization. It has mainly discussed about two basic skills on which employers focus, soft skills and technical skills (Grugulis and Vincent 2009). Problem: The main issue that has been discussed in the previously mentioned article is the preference of the recruiters is shifting from the soft skills to technical skills. According to the writers of the article, in recent time recruiters of the business organizations focuses more on the technical skills instead of the soft skills. The researchers have concentrated on exploring the reasons behind such practices (Grugulis and Vincent 2009). Key Ideas and Arguments: As per the article, in recent time, the employers concentrate on the technical skills of the employees while appointing them in any post. It helps skilled and talented employees to be appreciated by the authority. The writers claim that such practices mainly occur in the public sector. The competitive nature of the market has been increased drastically in past few years. It has led the organizational leaders to appoint some skilled and talented employees who have technical idea in the respective field. According to the report, the change in the nature of skill is the main reason for such practices. The report claims that, now a days skills include the capacity of team work, motivational power, judgement, leadership capabilities and so on. It has motivated employers to look for such employees that can stimulate the organizational performance by their technical skills. The report claims that there are some key issues with the soft skills, as it may influences discrimination in the work place. The writers have resented some examples of such workplaces where such discrimination occurs, such as- in call centres male employees are expected to meet their sales target whereas female employees are expected to perform in a significant manner. The study has provided some examples of renowned and large business organizations where soft skills are emphasised. The article has tended to distinguish between the soft skills and technical skills (Grugulis and Vincent 2009). Issues: Issues that must be enlightened from the study is that soft skills are mainly used in the case of women. They are allotted such tasks or such sections that suit their skills. However, the study has highlighted that it cannot enhance their position or reputation in the workplace. It will always distinguish them from other workers. Conclusion: As per the discussion, it can be concluded that there is a conflict between soft skills and technical skills. Employers are now a days looking for technical skills instead of soft skills as it will be beneficial for the future of their organization. References: Grugulis, I. and Vincent, S., 2009.
