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

(cheek) cell under a light microscope. The stain methods I am going to use are iodine for my onion cell and methylene blue for my cheek cell. Introduction All animals and plants are made up of cells. Animal and plant cells are made from millions of tiny cells‚ so small that we are unable to see them with our naked eye. Animals and plants have many features in common within a cell such as a cell membrane‚ cytoplasm‚ mitochondria‚ ribosomes and the nucleus. Plant cells also have a cell wall‚ chloroplasts

History of the Cell Theory Ryan Strehlein Cells‚ the make-up of all living things. Some cell are complete organisms‚ such as unicellular bacteria and protozoa. Other types of cells are called multicellular‚ such as nerve cells and muscle cells. Withen the cell is genetic material‚ Deoxyribonucleic Acid (DNA) containing coded instructions for the behavior and reproduction of the cell. The cell was first discovered by the 1665 English scientist Robert Hooke‚ who studied the dead cells of cork with

The Onion Cell Lab Background: Onion tissue provides excellent cells to study under the microscope. The main cell structures are easy to see when viewed with the microscope at medium power. For example‚ you will observe a large circular nucleus in each cell‚ which contains the genetic material for the cell. In each nucleus‚ are round bodies called nucleoli. The nucleolus is an organelle‚ which synthesizes small bodies called ribosomes. Ribosomes are so small you cannot see them with the light microscope

Define Stem Cells and give background information on them. Stem cells are a class of undifferentiated cells that are able to differentiate into special cell types. There are two types of Stem Cells: Adult Stem cells and embryonic stem cells. Embryonic stem cells come from embryos that are 3-5 days old. They are often taken from the umbilical cord. They are used more than adult stem cells. Adult stem cells mainly come from bone marrow. Their primary function is to maintain homeostasis by replacing

Stem cells are unique because they have the ability to generate new cells of any kind during early life and growth. There are about 200 different types of cells in the body; such as muscle‚ skin and brain cells. Most of these cells have to be repaired or replaced once in a while. For example our taste buds are replaced every 10 days‚ skin cells every couple of weeks and liver cells every 300-500 days. Stem cells serve as an internal repair system dividing essentially without limit to replenish

Sep. 21‚ 2014 Stem Cells Stem cells are the beginning of organism creation and have the potential to separate‚ becoming any kind of organism‚ endlessly. These cells have not gone through the process known as differentiation‚ which gives the cell a specific function. Technically‚ due to research over the recent years‚ scientists could grow certain organs with through stem cells because of the fact that these cells can be manipulated early on. There are multiple stem cells that have been determined
