A basic understanding of the cell and it’s functionality is something that an elementary schooler can understand. But what about cells that are either single-celled, multicellular, or even both? Do you know the similarities and differences? It is important to have a basic cognizance of the two main types of cells: eukaryotic and prokaryotic. Everyone should have a slight amount of knowledge about what all living matter, including ourselves, is made of. Although all cells seem similar at first, here are some noticeable similarities and differences.

Cell theory define Cells as the basis of life in the universe, all living organisms are made of cell, and all cells created by other old cells. There are many types of cells that can be categorize. Prokaryotic cell and eukaryotic cell. These two types of cell have similarities and differences.

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 aim of this exercise is to equip the student with the knowledge and skill necessary for conducting microscopic observations. It is also intended to teach the student the various sizes and shapes of several different types of bacteria.

Because eukaryote is not perceptible to the naked eye, we tend to neglect them. As a result of this, eukaryote help to furnish the growth of oxygen in the atmosphere, and take care of the decay of organic materials and nutrient cycling, and 3. Polyphyletic also known as algal evolve through separate endosymbiotic occurrence. As a result, this population is identified on the principle of a similar level of structure, and not on evolutionary origins (Plant and Animal

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.

Archaea are a group of single celled prokaryotic, so they don 't contain a nucleus. Archaea live in water especially salty region, and also come from animal stomachs. Archaea are also different from bacteria. Eubacteria are many different cells which belong to the group of prokaryotes. Eubacteria also have different types of shapes such as spirals and spheres. Eukarya are organisms that have cells with nucleus. The examples are protist, animal, fungi, and plants. Protista is part of eukarya that isn 't fungus, plant, or animal. Fungi are single and multi celled eukarya organisms that have cell walls, and they get nutrients by cellular digestion. Plantae is from the domain

A eukaryote is any organism whose cells have a nucleus and different organelles enclosed within the membranes. There are three distinct domain of organisms of nature which are bacteria, archaea, and Eukarya. Eukarya are eukaryotic cells that have membranes that are made out of unbranched unsaturated fat chains joined to glycerol by ester linkages. Not all of Eukarya have a cell wall, but the ones that do have a cell wall contains no peptidoglycan. The domain Eukarya has been partitioned into four supergroups, which are Archaeplastida, Alveolata, Excavata, and Unikonta. Human pathogens are found in Alveolata, Excavata,and Unikonta. “Excavata are unicellular species that usually have a feeding groove on one side of the cell and possess one or

Unlike these cells, Eukaryotes contain membrane-bound organelles, and also contain a variety of differentiated structures.1 Eukaryotes are categorized by the presence of a membrane-bound cell nucleus, along with a nuclear envelope, and chromosomes that contain the cell’s DNA.1 Eukaryotes contain a plethora of various organelles. Some organelles include: Mitochondria, Endoplasmic Reticulum, Golgi Apparatus, Lysosomes, and in plant cells, chloroplasts and vacuoles. Eukaryotes are the most common cell, and are found in all four kingdoms: Protista, Plantae, Fungi, and Animalia.1 Eukaryotes divide using either mitosis or

There are two basic types of cells, prokaryotic cells and eukaryotic cells. The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus. The nucleus is where cells store their DNA, which is the genetic material. The nucleus is surrounded by a membrane. Prokaryotic cells do not have a nucleus. Instead, their DNA floats around inside the cell. Organisms with prokaryotic cells are called prokaryotes. All prokaryotes are single-celled (unicellular) organisms. Bacteria and Archaea are the only prokaryotes. Organisms with eukaryotic cells are called eukaryotes. Animals, plants, fungi, and protists are eukaryotes. All multicellular organisms are eukaryotes. Eukaryotes may also be single-celled.

Cells are divided into two categories namely the Prokaryotes and Eukaryotes. These two have varying differences between them. Speaking in simple cell biology words, prokaryotes are primitive, simple organisms that lack membranous cell organelles. The opposite of this are eukaryotes, which are advanced and complex organisms having membrane bound cell organelles. Seemingly simple in structure and markedly different from eukaryote and protist organisms, prokaryotic cells are believed to have been amongst the first on the Earth and very well may out-survive all other organisms. Examples of prokaryotes are bacteria and archaea and eukaryotes include fungi, animal and plant cells.

The terms ‘eukaryote’ and ‘prokaryote’ were introduced Edouard Chatton in 1925 (Chatton, 1925, cited in Sapp, 2005). Eukaryotes, according to the online Oxford Dictionaries is a cell in which DNA is arranged in chromosomes that are “contained within a distinct nucleus”. The name prokaryotes is also defined by the Oxford dictionary as an organism that does not contain a ‘distinct nucleus with a membrane’. These two terms highlighted a very important difference between the two cells; eukaryotic cells had a true nucleus surrounded by a membrane but the prokaryotes did not. The following essay seeks to compare and contrast typical prokaryotic cells to typical eukaryotic cells.

The above diagram shows a prokaryotic cell. These cells have a simple cell structure and are thought to have been the first cells to have appeared on earth (Clark, 1998). Most prokaryotic cells are single-celled and none are found in living animals, it is mainly bacteria or algae that it is found in. The chemicals and enzymes are contained in the cytoplasm and are used for the cells growth. The cytoplasm is a jellylike mixture that is packaged into the membrane that forms the cell boundary. This cell does not contain a nucleus. The DNA is also attached to the plasma membrane.

Cells are the basic unit of life, they are in all living organisms (Plants and Animals), and arise from the division of existing cells. Cells contain information which control their activities and are capable of independent existence as long as it has suitable conditions.
