Recommended: Difference of prokaryotic and eukaryotic
There are two major types of cells, Prokaryote cell and Eukaryote cells. Prokaryote and Eukaryote Cells are said to be the most vital differences that are present in organisms. Millions of years ago, prokaryotes were one of the only life forms on our planet. Now they have given birth to eukaryotes, due to evolution and mutation. Each cell controls and deals with several different tasks in all living things. Unicellular organism (such as bacteria and archae, also known as archaebacterial) are single celled and also known as prokaryote cells. Multicellular organisms, which include multiple cells, are complex and are known as eukaryotic cells. If one were to ask to simply state what a prokaryote is, without getting too technical, one would state that a prokaryote is pretty much a microscopic bacterium without a nucleus. What is this microscopic …show more content…
Prokaryotic cells are much more easy in structure while eukaryotes can be a little more complicated. Prokaryotes do not possess a nucleus as stated above. Eukaryotes do possess a nucleus. They are also smaller than eukaryotic cells. While eukaryotic cells have a nucleus, prokaryotic cell do not. Prokaryote cells are made up of one cell. They reproduce through asexual reproduction. This reproduction process is called binary fission. Eukaryotes reproduce through mitosis or meiosis. Meiosis is the cause of cells that are sexually reproducing, while mitosis duplicates the initial cell. Ribosomes that are found in prokaryotes are much smaller than those found in eukaryotes. DNA, that prokaryotes possess, are single strands. DNA found in eukaryotes have many strands. Microtubules, which helps a cell replicate, are not found in prokaryotes, however, they are present in eukaryotes and help them in reproducing. Prokaryote cells are unicellular and eukaryote cells are mostly multi
There are many different cells that do many different things. But all of these cells fall into two categories: prokaryotic and eukaryotic cells. Eukaryotic cells contain a nucleus and are larger in size than prokaryotic cells. Prokaryotic cells do not contain a nucleus, are smaller and simpler than eukaryotic cells. Two of their similarities are they both have DNA as their genetic material and are covered by a cell membrane.
Cell cycle events portray some differences between different living things. In all the three living things, their cells divide, a process referred to as mitosis. The mitosis stage differs and it encompasses four phases. During development, the cell cycle functions endlessly with newly created daughter cells directly embarking on their path to mitosis. Bacteria cells separate forming two cells after every thirty minutes under favorable conditions. However, the eukaryotic cells take quite longer compared to bacteria cells to develop and divide. Nevertheless, in both animals and plants, cell cycle is usually highly regulated to prevent imbalanced and excessive growth. Both animals and plants are known as eukaryotes meaning that their DNA exists inside their cells’ nuclei. Therefore, their cells as well as mitotic processes are similar in various ways (Eckardt, 2012).
Eukaryotic Cells are Deemed as a Result of the Evolution of Symbiotic Prokaryotes Both Prokaryotic and Eukaryotic cells over time have sustained very dynamic changes from one another. More specifically we have seen the appearance of a more complicated and organized cell structure, the nucleus. However the big question amongst scientists today is how did these changes first occur? A fundamental concept of this evolution is the belief in the natural progression 'from the simple, to the more complex.' However one popular theory that argues that Prokaryotic symbiosis was responsible for forming the Eukaryotic nucleus is the 'Endosymbiotic Theory' this theory was first proposed by a former Boston University Biologist known as Lynn Margulis in the 1960's.
Bacteria are single celled microbes. Bacteria reproduce by binary fission. In this process, the bacterium, which is a single cell, divides into two identical daughter cells. Binary
Prokaryotes and eukaryotes are organisms that are divided by their basic biological structure - the presence or lack of membrane-bound organelles. However, they can be defined and discriminated from one another according to certain key cellular functions and their respective differences: the way their DNA is stored and replicated, how they respire or photosynthesise, process their RNA transcripts or respond to foreign nucleic acids.
Eukaryotic cells, whether from animals, plants, protists, or fungi, are the most structurally advanced of the major cell types. Eukaryote are single-celled or multicellular organism whose cells contain nucleus and any other structures (organelles) enclosed within the membrane that perform specific functions. The surface of the cell is covered with a thin film or plasma membrane, which is the boundary that separates the living cell from its nonliving surroundings. Plasma membranes are composed mostly of proteins and lipids (Simon, 02/2012, p. 59-60).
In the beginning of the creation of Earth volcanoes erupted all over the planet. During this period there was a time where a brief cooling period was allowed to take place. When this period took place evaporation caused a downpour of rain which flooded the ocean creating the ocean. At the time that ocean was averaged at 3,000 degrees Fahrenheit. Around this same time an asteroid so powerful hit the Earth knocking off a large chunk of it. This chunk became the moon which at the time was twice as close as it is today. The hitting of the planet Earth cause such a shake that many new undersea volcanoes began spewing forth molten rock and gasses. These gasses and other particles formed on the oceans surface and with the moon being so close were smashed together by strong and violent waves.
What are microorganisms? They are organisms that you have to view with a microscope. The three that I will be discussing are bacteria, viruses, and prions. Of the three, a bacterium is the only one that can be helpful to us in many situations, and they are also the most diverse organism on the earth. The structure, reproduction, and the diseases bacteria, viruses, and prion cause are all different. Let’s begin to compare these microorganisms.
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.
Cells are able to grow and reproduce. Cells reproduce by splitting and passing on their genes (hereditary information) to Daughter cells. The nucleus always divides before the rest of the cell divides. Therefore each daughter cell contains their own nucleus. The nucleus controls the cells activities through the genetic material DNA. The cells in a body are all the same except the gametes they were all made from one cell, the Zygote. This is the cell that was formed when two gametes from your parents fused.
Prescott, Harley & Klein (1990) describe bacteria as prokaryotic cells (cells that lack a true membrane enclosed nucleus). Bacteria are both small and simple in structure; they usually are between o.5 and 5cmm yet they have many characteristic shapes and sizes. Some bacteria are circular or oval shaped, they are known as cocci bacteria. Other bacteria are rod-shaped, they are known as bacilli bacteria, and some bacteria are spiral and coil-shaped and it is know as spirilla bacteria.
The Animal Cell is a little bit different than the Plant Cell for only a couple of reasons. One is how the Plant Cell has a cell wall and the Animal Cell doesn’t. The cell wall protects and gives structure to the cell. Then there is the Nucleus, which serves as a control center for the cell. Inside the Nucleus there are one or more Nucleoli. They are dense, granular bodies that disappear at the beginning of cell division and reappear at the end. Then you have the Cytoplasm. This is the watery material lying within the cell between the cell membrane and the nucleus. The Cytoplasm also contains organelles, which have specific functions in the cell metabolism. Then there are the Golgi Bodies, which serve as processing, packaging, and storage for the cell. These organelles package and ship things out. Another parts of the cell, a very important one in fact, are the Lysosomes. These organelles are used to break things down and contain enzymes.
Every cell, either prokaryotic or eukaryotic all contain basic cell parts. They are: a plasma membrane, cytoplasm, DNA (the genetic material), and ribosomes. Prokaryotic cells have a simple structure and they are usually smaller than eukaryotic cells. Also, most prokaryotic cells contain a cell wall. In addition to having the basic cell parts, eukaryotic cells also contain a membrane-bounded nucleus and cell organelles.
Prokaryotes include several kinds of microorganisms, such as bacteria and cyanobacteria. Eukaryotes include microorganisms as fungi, protozoa, and simple algae. Virus cells often consist of just a nucleic acid either DNA or RNA in a protein capsule. Viruses are considered neither prokaryotes nor eukaryotes because they lack the characteristics of living things, except the ability to replicate (which they accomplish only in living cells).
It is a single-celled organism that is not visible to the human eye, which means it can only be seen with a microscope. Bacteria are classified as Prokaryotes. They make their own food from the sunlight and can absorb food from the materials that they live on.
