Cell biology

Cell biology 1. A cell is eukaryotic because  Is generally larger and much more sophisticated than prokaryotic cells due to the presence of a complex series of membranes that divide a typical eukaryotic cell into compartment.  Eukaryotic cell has an organized nucleus with a nuclear envelop.  Has membrane bound organelles  Contain linear DNA molecule that are larger than the (circular) DNA molecules in prokaryotic cells and, in association with proteins, form structures called chromosomes. 2. Insulin, a peptide hormone, which is released into the blood by the pancreatic beta cell when the blood sugar level is too high (hyperglycaemia) in a regulated secretion pathway to maintain normal blood sugar level (Normoglycaemia), and its synthesis…

I plan to pursue my love of Biology by attaining a degree in Biochemistry and Cell Biology. I hope to further my knowledge in the clusters The Amazing Red Blood Cell, and Living Oceans in Climate Change at UCSD. While the former appeals to my determination to discover innovative ways to remedy human ailments, the latter appeals to my desire to address the pressing issue of climate change. My interest in biology began in freshman year. We learned about the different parts to the cell, and I was…

The next topic a student should be schooled in is cells and cellular biology. While cells are the building blocks of all living organism, scientists have confirmed that there are actually different types of cells depending on the organism. The two main classes of organisms are the prokaryotes and the eukaryotes. The prokaryotic is the simpler of the two and are the one-celled organisms such as bacteria and archaea. The interior of a prokaryotic cell consists of a main nucleoid, which contains…

Cell Theory is used to describe cells as the basic building blocks of all living things. All organisms are composed of one or more cells and have an outer layer of a plasma membrane (or cellular membrane), which acts as a barrier that divides the cell from its surrounding environment. The plasma membrane of a cell acts as a physical barrier and regulates the exchange of materials with its surroundings. It is a permeable membrane that surrounds the cytoplasm. The contents held within the plasma…

Caulobacter Crescentus is a dimorphic, α-proteobacterium found in oligotrophic environments. Their dimorphic cell cycle produces two morphologically and functionally different daughter cells, known as the stalked cell and the swarmer cell. The stalked cell remains anchored to the substratum and is sessile, while the swarmer cell is motile. Upon chemotaxis, the swarmer cell disperses in search of nutrients. Once sufficient nutrients are located the cell cycle can continue. In the early phases of…

In biology, tonicity refers to the salt-water balance of a system between a permeable membrane such as the cell membrane (Campbell, 132). Tonicity is directly related to the movement of water from an area of lower solute concentration to an area of higher solute concentration, in order to reach a dynamic equilibrium. The three general states of tonicity are hypo-tonic, iso-tonic, and hyper-tonic. Hypotonic solutions are lower in concentration as compared to another solution. There will be a net…

the solution, the less cells going through hemolysis. Thus, there is not enough water entering the cell to produces the cells to burst. The main clue is when the water is completely dilute, so we have 100% hemolysis. Hemolysis is correlated with the behavior of the cell specifically refers as hypotonic. The results correlated with the raised hypothesis, the data overall represents the hypothesis. The different osmolality has a relationship with the % hemolysis. Starting with the distilled water…

deteriorate tumor cells through growth inhibition and apoptosis inducing. Furthermore, SEB plays critical roles against different cancers by immune responses activation (25, 26). In the present study, we have documented that BM-MSCs are a strong factor with noticeable effects on the biology of myeloma cells. Also, BM-MSCs could change results of SEB on myeloma cell line. Furthermore,…

With a cell inside of a hypotonic solution, the amount of a solute outside of the cell is less than the amount of solute inside the cell. The cell has more of the solute on the inside, which means the water will move into the cell. Water will move by osmosis to the area of greater solute concentration in order to balance the amount of solute and water. If a cell receives too much water as a result of a hypotonic environment, it may lyse, or burst, because of the influx of water. Plant cells…

Q1:What sort of environment (hypertonic, isotonic, hypotonic) does consuming excessive amounts of pure water create in the body fluid that surrounds your cells? What effect would this have on your cells? A1: Consuming too much water would cause your cells to become hypotonic. The cells would experience a higher than normal percentage of H2O and consequently have a smaller than normal percentage of solute. This would cause the cells to eventually flood, swell, and burst. Q2: What types of…
