Prokaryote Vs Eukaryotes Essay

Prokaryotes are the primitive, simple cells of bacteria and their bacteria-like Archaea. Eukaryotes, which include the most advanced cells of animals, plants, fungi, protozoan, algae, and slime & water molds.

Well prokaryote is the name given to organisms that are made up from cells that lack a cell nucleus or cells that lack any membrane-encased organelles (a specialized subunit within a cell). In lamens terms, in prokaryotes, the DNA is not bound or held together inside a nucleus. Prokaryotes also only have a single loop DNA. Last but not least prokaryotes are divided into groups or domains but more about that in a minute.

The purpose of this study is to identify four unknown organisms. The unknown organisms have been assigned randomly to six-research groups by Professor Hoffman. Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya.

The distinction was made from Prokaryotes Bacteria and Archaea which are classified different to the domain of the Eukaryotes and there four kingdoms (animals, plants, protists and fungi). The Prokaryotes meaning comes for the Greek word meaning (pro) “before” and (karyon) meaning “nut or kernel” Most of the prokaryotes can be seen as a unicellular organisms although the myxobacteria have been seen in different stages in their life cycles like in colonies of cyanobacteria. (Also call blue green algae) Which are predominantly photosynthetic and also fall into prokaryotes Eubacteria kingdom. Although you can find some Algae as Eukaryotes domain. Like most algae’s that are photosynthetic can produce oxygen gas as a by-product. Theorists have proposed that this could have been the link to change the early atmosphere on earth into and oxidizing one that enabled the stimulation of the biodiversity of life that we see today.

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

A cell is defined as the smallest and most basic 8nit of life-microscopic, self-contained units enclosed by a water repelling membrane. The human body is composed of approximately 100 trillion cells. We also learned that a genome is the complete set of genes of an organism, or also known as genetic information. We learn that a gene is a segment of DNA that codes for distinct genetic characteristics, such as having O-type blood or a dimpled chin. The cell theory plays a large part in chapter 3 because chapter 3 is all about cells. Cell theory, is one of the unifying principle of biology. This concept has two main parts: Every living organism is composed of one or more cells, and all cells living today came from a pre-existing cell. The cell theory pretty much states that cells come from other cells, and that all individual cells are alive. It also states that all living and only living things are made of cells. We also learn about prokaryotes and eukaryotes. Prokaryotes are any of one of the two major groups of living organisms. Only bacteria and archness are prokaryotes are prokaryotes. Prokaryotes are often known as “pre-nucleus” organisms. Prokaryotes are approximately ten times the size of eukaryotes, lack membrane bound organelle, and are the oldest fossils. Prokaryotes are approximately 3.5 billion years old. Eukaryotes are one of the two major groups of living organisms. They include animals, plants, fungi, and protists. These eukaryotes are known as “true-nucleus”. Eukaryotes are approximately ten times the size of prokaryotes, have membrane bound organelles, and are also the oldest fossils and are approximately 2.1 billion years

In the replication process of DNA, there are similarities between the process of replication of a Eukaryote cell and Prokaryote cell. There are also differences in both processes. The most notable difference would have to start with the cell themselves, which may add to additional differences in the processes. A prokaryote is a more simplistic cell with less DNA and a Eukaryote cell is much more complex with vast amounts of DNA.

Prokaryotes were the earliest organisms on earth. Some of these organisms were photosynthetic which helped from the accumulation of oxygen gas in earth’s atmosphere (This actually hurt a lot of the prokaryotes over). Prokaryotes are found almost everywhere, including bodies of other organisms. They even live in extremely harsh environments like areas of high salinity or temperatures very high or low. They reproduce extremely fast which means they evolve fast and why they are very diverse. This is why bacteria can build up resistance to antibiotics very quickly.

An prokaryotic and eukaryotic cell are different in many ways. A prokaryotic cell means a microscopic single celled organism that has neither a distinct nucleus with a membrane,and mitochondria,or an membrane bound organelle. The prokaryotic cell is like an apartment, it supports the person with living space, but is small and simple at the same time. An eukaryotic cell is any organism whoose cell contains an nucleus, and other membrane bond and organells. An example of an eukaryotic cell is an mansion.

Prokaryotic Cells All living things are made of cells, and cells are the smallest units that can be alive. Life on Earth is classified into five kingdoms, and they each have their own characteristic kind of cell. However the biggest division is between the cells of the prokaryote kingdom (monera, the bacteria) and those of the other four kingdoms (animals, plants, fungi and protoctista), which are all eukaryotic cells. Prokaryotic cells are smaller and simpler than eukaryotic cells, and do not have a nucleus. Prokaryotic means 'pre-nucleus' and eukaryotic means 'true nucleus'.

Eukaryotes DNA is divided between a set of different chromosomes, in particular the human genome is distributed over 24 different chromosomes in the nucleus. Each chromosome consists of a single, long linear DNA molecule associated with proteins that wrap up the DNA into a more compact structure: the chromatin, which derives from the Greek "chroma" meaning "color", for its staining properties.

There are many ways in which gases interact with proteins throughout both eukaryotes and prokaryotes. Examples of this include nitrogen and carbon assimilation in plants, and oxygen in oxidative phosphorylation. However, in this essay I will focus on the interaction of carbon dioxide and oxygen with rubisco, nitrogen fixation by nitrogenase in bacteria, and oxygen transport, as these processes illustrate the variety of reasons why gases interact with proteins.

Classification is the method used by scientists to order living organisms. All species have a unique classification that results in a binomial name. classification is used to make it easier for different species to be identified by scientists. The current system, the Three Domain System , groups organisms primarily based on differences in ribosomal RNA structure. Ribosomal RNA is a molecular building block for ribosomes .  Under this system, organisms are classified into three domains and six kingdoms . The domains are Archaea, Bacteria, and Eukarya. The kingdoms are Archaebacteria (ancient bacteria), Eubacteria (true bacteria), Protista, Fungi, Plantae, and

In this lab, we observed different prokaryotic and eukaryotic cells, and then we observed a termite gut to see the different unicellular microorganisms that it contained. The purpose of this lab is to observe living and prepared bacterial cells, then describe their morphology, observe and describe the primary features of the eukaryotic cell, and to investigate and observe the organisms involved in a symbiotic relationship. By observing these things, we are hoping to find out what we should expect to see in yogurt bacteria. In order to predict this, we must first know the differences between prokaryotic and eukaryotic cells. Prokaryotic cells are organisms that do not have a cell nucleus, or any other membrane-bound

Primarily, the Archaea were once believed to be just another rare group of bacteria, because like bacteria, they are single-celled microscopic prokaryotic organisms with no membrane bound nucleus (http://www.fossilmuseum.net/Evolution/archaeaevolution.htm). Despite the similarities in the cell structure of Eubacteria and Achaea, molecular research by Dr Carl Woese and his co-workers indicated that they differ significantly on the molecular level (Bacteria in Biology, Biotechnology and medicine, Paul singleton). In this essay, am going to discuss the differences and similarities in the fundamental cellular feature of both organisms.
