Cell Fractionation * Cell Fractionation: takes cells apart and separates the major organelles and other subcellular structures from one another. * Tissue cells are the first one to be homogenate or broken apart. * Plasma membranes are broken up so that there internal contents spill out and mix together and this is called homogenate. * Homogenate is in spun in a higher rate of speed in a process called centrifugation. And that speed can vary that why it’s called differential

Recent studies of stem cells have played are very important because they show promise in helping man solve or at least grasp the solution to the diseases that have haunted him since his early days of conscious. The idea of stem cells is kind of a simple idea. This brings us to the first promise‚ not only are stem cells able to be taken from the human body‚ but scientists are now able to grow these cells in labs. The most worried over part is that when obtaining the cells‚ it doesn’t always

The fluid mosaic model of the cell membrane. What is the fluid mosaic model? The fluid mosaic model is a model conceived by S.J. Singer and Garth Nicolson in 1972 to describe the structural features of biological membranes. The membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid‚ but more like a ’fluid’. The membrane is depicted as mosaic

Stem cells Nowadays‚ stem cells are the hottest topic in the medical field. More and more researches are performed to investigate these mystic cells. In order to go deeper into this topic and fully understand it‚ let’s first take a look at the stem cells themselves‚ their origins and characteristics which make them so unique and crucial for the medical field. Stem cells are very complex and complicated‚ and‚ that is why‚ it takes a lot amount of time to get to the bottom of their structure to be

The Xylem is part of a plant‚ which is a hollow tube with spiral thickening of lignin around the wall giving strength‚ which is continuous throughout the whole plant. The difference between the Xylem cell and other cells is that the Xylem is dead and has no cytoplasm. The Xylem is responsible for transporting water and certain nutrients form root to plant. Phloem carries soluble organic material i.e. food for the plant. The top of the plant is in the light‚ conducting photosynthesis and helping the

regions of membrane lipids involved in cell signaling are called lipid rafts. • Hopanoids are sterol-like molecules found exclusively in bacteria. • Membranes from cells grown in media enriched with stearate are less fluid than normal membranes. This is because the membranes have more saturated fatty acids. • The functions of the biological membrane are : • They contain receptors for the detection of external signals • They provide a means of cell to cell communication • They regulate movement
