    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…

    I was first introduced to basic cell biology in sixth grade. As I learned more about the field of cell biology, my interest grew and adapted to include genetics, cellular oncology, and cell anatomy. The following year, seventh grade, I wrote a research essay about the effects of cancer at the most basic level: cellular. I discussed this research with nearly a hundred people, explaining different processes and systems to people who had no interest in what I was explaining in great detail. In…

    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…

    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…

    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,…

    Solute Plant Cells

    • 429 Words
    • 2 Pages

    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…

    Discussions Bag A stimulates cell whose contents are hypotonic to its environment. The situation is because the concentration of the dissolved substances in the cell is less than the surrounding media. In this case, the cell contents contain 1% sucrose solution that is less concentrated than the 50% surrounding media. Therefore, a large concentration gradient develops between the two media. Consequently, because of the high concentration gradient, the bag loses water faster and this leads to its…

    and Latrunculin on endocytosis. Introduction Phagocytosis is a process in which cells engulfed foreign materials. Eukaryotic cells can engulf different particles and solutes from their environment using a variety of mechanisms called endocytosis. Some cells can carry out large endocytic processes called phagocytosis and micropinocytosis. These processes can internalize particles (>0.5um) whereas internalization of fluids through micropinocytosis mechanisms or solute into vesicles for size…
