Although these two cells share a lot of similarities there are also many differences between the common prokaryotic and eukaryotic cells, however more specifically I will be exploring how the structure relates to the function of an animal cell and a non-photosynthetic prokaryotic cell, and it is explained that, “analysing a biological structure gives us clues about what it does and how it works” (Campbell et al: 2014, p.52). The structure and the function of a cell generally aren’t one without…

Conditions required for bacterial growth and therefore their reproduction are referred to as Extrinsic and Intrinsic factors. Bacteria can grow anywhere in the world including animals and plants, depending on their characteristic, type and so on. Knowing that, it seems like bacteria can grow everywhere once they have correct conditions. However there are a lot of factors that can affect bacterial growth. The factors affecting bacterial growth are the internal and external conditions of the…

In bioturbation literature, it is often assumed that microbially-mediated processes have been affected by bioturbation, with no analysis of the microbial community (Kristensen, 1984, Kristensen, 1985, Kristensen and Blackburn, 1987, Gilbert et al., 1998, Christensen et al., 2000, Michaud et al., 2006, Bonaglia et al., 2014). For example, variations in microbial nutrient remineralisation (Renz and Forster, 2013), and declines in sediment functioning under reduced pH conditions (Widdicombe and…

Florida Beaches Home Vibrio vulnificus In the months of April and May, eight Vibrio vulnificus cases were reported with two of them resulting in death this year (Galimberti). Vibrio vulnificus is a flesh-eating bacteria that thrives in areas of warm water, lakes, rivers, and oceans. Florida beaches tend to be hot during the summer and autumn which makes Florida beaches a great place for Vibrio vulnificus to live in. So what exactly is Vibrio vulnificus, how is it transmitted, what are the…

Support the Endosymbiotic Theory Gianna Melendez Chamberlain College of Nursing Support the Endosymbiotic Theory The endosymbiotic theory proposes that eukaryotes formed from the union of small aerobic prokaryotes with larger anaerobic prokaryotes, which form organelles. The smaller prokaryotes were not destroyed by the larger cells, but instead became internal parasites that remained surrounded by a vesicular membrane of the host. The theory proposed that mitochondria are the…

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…

Apoptosis or Programmed cell death (PCD) is a regulated process of cell death where unwanted or damaged cells are eliminated. It is an important component of a cell’s growth, development, and homeostasis in multicellular organisms. The programmed cell death process consists of the cell’s cytoplasm condensing and within an hour getting phagocytized by the neighbouring cell. Throughout the whole process, the cell’s membrane is still intact and this prevents the contents of the cell from getting…

‘Revenge of the microbes’ by Abigail A. Salyer and co-author Dixie D. Whitt are both professors in the department of Microbiology at the University of Illinois. After thorough research by the professors, this great piece was published. This masterpiece, happens to be a reliable source for mere educative information about the microbiological world we find ourselves in but it could also be used as a good source for rich information about the activities of microbes and the role they play in our…

The main idea of this podcast was the identification of everyone’s unique microbiome, and how does it change when introduced to new microbes. First, was the fact that every individual has their own microbial ecosystem specific to themselves. Where one lives and what someone eats can define the makeup of these ecosystems on the skin, in the mouth, and in the gut. These items are relevant to the classroom in that we must be aware of this dynamic ecosystem, especially when prescribing antibiotics.…

Bacteria are single-cell organisms can appear everywhere. The bacteria live in every climate and location on Earth (in the air, water or land...). When prompted to "bacteria", many people assume that it means negative, but the bacteria perform many important functions for the organism and the environment. The majority of bacteria harmful to humans but still have some kind of beneficial. In the gastrointestinal tract of humans, the good bacteria that aid digestion, producing vitamins and immune…
