Prokaryotes And Eukaryotes Essay

bacteria to gain either of the traits the plasmid had to be present in the first place, because the GFP gene is inside the plasmid. If arabinose is not in the media in which the bacteria was growing on then the GFP gene could not turn on, thus the bacteria can not glow. This is why the LB/amp/ara plate was the only one to express both traits(antibiotic resistance and glowing). The second part to our hypothesis was that using HIC,GFP would be purified and the final tube would express GFP under an ultra violet light. Contrary to what we expected the final tube nor any of the columns expressed the ability to glow under ultra violet light.

Bacteria can be classified as gram positive or negative (difference in call wall). Gram positive bacteria have a thick cell wall of peptidoglycan (“polymer of disaccharides cross-linked by shorts chains of amino acids”), and stains purple after the staining procedure under a microscope (Todar, Kenneth,

For example, Clostridium botulinum can cause an issue in can foods. By knowing the previous information, one can avoid certain cans and prevent sickness. Each bacteria has specific characteristics that is unique to the certain strain, which makes identification possible. This Unknown Identification Lab was performed in a series of three days. The lab contained the following tests: Gram-staining, Blood Agar Plate, Mannitol Salt Agar, Levine Eosin Methylene Blue Plate, and Hektoen Enteric Agar Plate.

Lipids are the primary determinants (deciding factor) of membrane structure, while proteins carry out membrane functions. 4. Which organelles are surrounded by plasma membranes? (Eukaryotic cells possess additional internal membranes that surround organelles like) the nucleus, the endoplasmic reticulum, the Golgi apparatus, mitochondria, and lysosomes. 5.

The first life was thermophiles, a one-celled organism called archaea. The archaea went through evolution, and adapted to the harsh environment, therefore becoming the

The Yertis Pestis bacteria cell is a bacteria cell, which means that it is a very small cell. It’s smaller than a lot of plant and animal cells, but bigger than most viruses. The cell has relatively few organelles. It has a cell membrane, cytoplasm, and ribosomes. Instead of a nucleus, it’s genetic material is floating around in a tangled string in the cytoplasm (Cells and Heredity 24).

Bacteria is where all the other kingdoms branch off from. Though Bacteria and Archaea are both prokaryotes, their genes are less than half related. Bacteria have its pros and cons for life on earth as some of them are good for the environment such as, food production, medicines, pest control, and etc. However, the cons are they can cause diseases, pathogenic, and etc. Without bacteria there will be no life in the world, as it is responsible for beginning everything.

Cellular world can be divided into two types, depending on the presence of nuclei inside cells. Eukaryotic cells have a well-defined nucleus surrounded by a nuclear envelope, whereas prokaryotic cells lack this compartment. All bacteria are prokaryotes. Bearze (2015) provided information about the Bacterial Cell Structure and Function. Vibrio cholerae is a gram negative, non-spore forming, curved rod that is oxidase positive.

The larger, more complex cells are eukaryotic cells because they have more organelles with more functions. The smaller, simpler cells are prokaryotic because they have fewer functions and organelles. My box represents a eukaryotic plant cell. One of the advantages of having a box as a plant cell is that it represents the cell

Domain: Eukarya This domain contains all organisms that have eukaryotic cells, including members of the kingdoms Protista, Fungi, Plantae, and Animalia. This means that they store DNA in the nucleus within each of their cells. Kingdom: Animalia All members of this kingdom are multicellular and heterotrophic, in other words, they are consumers. They do not have cell walls, and most of them are mobile for at least some part of their lives. Aside from these characteristics, kingdom Animalia is incredibly diverse.

However, when these bacteria are grouped together to have high cell density, the molecules they secrete amount to a certain number, and once that number is reached, the behavior of that bacteria is switched on and in this case, bioluminescence is created. Similarly, in my project, I am screening the anti bacterial activity using oils. Before I use the oil, I have to culture the bacteria overnight so that I could use them in the plates after 16-18 hours of incubation. Based on the talk, I believe that I have an idea on how bacteria grow. This Ted Talk has inspired me about science in numerous aspects.

Bacteria that causes disease are called pathogens. The disease is caused by a poison called exotoxin and endotoxin produced by the bacteria. Another microbial life are protist. They are unicellular eukaryotes. Types of protist includes protozoans and slime molds.

Approximately 60-90% of the Gram-positive bacterial cell wall is made up of peptidoglycan and interwoven teichoic acid, while only

Archaea are particularly numerous in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet. Archaea are a major part of Earth's life and may play roles in both the carbon cycle and the nitrogen cycle. No clear examples of archaeal pathogens or parasites are known, but they are often mutualists or commensals. One example is the methanogens that inhabit human and ruminant guts, where their vast numbers aid digestion. Methanogens are used in biogas production and sewage treatment, and enzymes from extremophile archaea that can endure high temperatures and organic solvents are exploited in

Bacteria usually have capsules, but archaea rarely have one. Inside the prokaryote is cytoplasm and a nucleoid. The nucleus is not enclosed inside of a membrane in prokaryotes. The cell may have appendages to adhere to certain surfaces or for motility. The prokaryotic cell is smaller than the eukaryotic cell and has different qualities that make the cell less complex than a eukaryotic cell.
