Prokaryote

transpired around 4.6 billion years ago. • 3.5 Billion years ago: Ancient fossils from around this time period provided evidence of a bacteria-like organisms known as Prokaryotes. This ancient cell was first founded in the 1970’s in among fossilized rocks from Australia and contain no nucleus. • 2 Billion years ago: A more complex prokaryote arises with a skeleton like structure similar to that of blue-green algae. It takes the shape of blue-green chains and is far more developed than a bacteria…

bacteria to bacteria through the exchange of their genetic material using some of the methods of horizontal gene transfer. As a result, the resistance acquired by one pathogen can be passed to other pathogens. 2) Describe conjugation in prokaryotes. Conjugation in prokaryotes is the method used to transfer genetic materials from alive donor cells, and is mediated by pili. Pili are proteinaceous tubes outspreading from the surface of a cell. The cells that are the donor during conjugation have…

bacteria. One of the main difference between archaebacteria and eubacteria prokaryotes is that archaebacteria is ancient. Due to the ancientness of archaebacteria, they can survive in extreme environments where most organisms cannot (9). The prokaryotes in these two domains also differ in the structure of their cell wall. Prokaryotes that contain peptidoglycan in their cell wall belong in the domain bacteria while prokaryotes in archaea do not contain peptidoglycan (9). Archaebacteria membranes…

What are the processes involved in cellular respiration? How do enzymes perform an important role in the mitochondria? How does the mitochondria use chemiosmotic gradients? How did the mitochondria evolve? The mitochondria are organelles found within eukaryotic cells, that produce energy for the cell. There are many chemical processes and important molecules involved in the mitochondria. Cellular respiration is the chemical process that makes the energy needed for the cell in the form of ATP.…

Microbes, which are knowns as microscopic organisms, can be found everywhere and have interactions with most of living things and non-livings things. Also, it causes either positive or negative impacts within these interactions. Certain types of microbes play a big role in all ecosystems on Earth, such as bacteria and fungi in order to not only maintain the life cycle on Earth but also helpful in human activities. Therefore, this essay is aiming to identify the role of these groups of microbes…

Both archaea and bacteria share the following similarities, they are both prokaryotes, without any complex cell structure. When looking through a microscope they are both identical in appearance to include shape and size. They both reproduce using binary fission, and move around using flagella. Archaea and bacteria have cell walls on the outside, which provide support, and lets Archaea and bacteria are both prokaryotes, meaning they do not have a nucleus and lack membrane-bound organelles.…

The simple definition of Eukaryotes is that they are any organism whose cells contain a nucleus and other membrane enclosed organelles. Taxonomically, Eukaryotes belong to the taxon Eukarya. The three types of eukaryotic microbes are fungi, protozoa, and algae. Because the three types of eukaryotic microbes are all composed of eukaryotic cells, they have basic similarities in cellular structure, including the presence of a nucleus. However, these types of microbes do differ in many significant…

For my project, I chose to make an illustration. In the picture I have a breast cancer ribbon, a pot of boiling water, a prokaryote, a chromosome, a pedigree, and a factory to represent human impact, a flower to represent photosynthesis, a food chain, an energy pyramid, an embryo, humans evolving, a biomolecules chart, and the phases of mitosis. I drew a breast cancer ribbon because we talked about different types of cancer. There are many factors that go into the diagnosis of cancer. A lot of…

Prokaryotic cells include bacteria that includes pathogenic and nonpathogenic prokaryotes that can be found in soil or water. The six types of bacteria include Proteobacteria, they are gram negative and are the largest classification of all of the bacterias. Proteobacteria has five classes which are alpha, beta, gamma and delta. The…

Gold is widely used in modern day medicine to treat disorders. This is because gold is very resistant to bacteria. Bacteria are microscopic single-celled organisms. Bacteria are prokaryotes, meaning the entire organism consists of a single cell with a simple internal structure. The DNA of a prokaryote is neatly packed in the nucleus. The bacterial DNA floats freely in a twisted thread-like mass called the nucleoid. Gold is unaffected by almost everything. The only materials that can affect gold…
