The cell‚ which is the smallest unit of life‚ is surrounded by a plasma membrane. The plasma membrane functions somewhat like a wall‚ as it keeps the internal contents from the external environment. Just like a wall‚ the membrane is also somewhat permeable‚ except that the membrane takes a much more active role in determining what is allowed in to the cell and what is kept out. The plasma membrane is a very thin structure‚ which has some very important tasks. One of the main tasks that it performs

coverslip was treated with the control solution‚ and the other was treated with the X drug. Then‚ in order to preserve the cell‚ methanol was added to both coverslips. Since methanol coagulates proteins‚ it was also used to permeabilize the cell membrane. Once the cells were fixed and permeabilized‚ blocking buffer was added to each coverslip to block the nonspecific antibodies in order to keep them from binding to everything in the cell. Then the primary mouse antibodies were added to the cells

An Evaluation of “A Study of Prisoners and Guards in a Simulated Prison” “A Study of Prisoners and Guards in a Simulated Prison” is a research article written by Craig Haney‚ Curtis Banks and Philip Zimbardo. The basis of the psychological experiment performed was to study and research the effects of being a prisoner and a guard in a simulated prison environment. The focus being the patterns and behavior characterized by both parties and to investigate how easily the subjects were susceptible to

13 THE MEMBRANES OF DIFFERENT TYPES OF CELLS ARE INVOLVED IN MANY DIFFERENT FUNCTIONS – 25 MARKS Membranes are found in all organisms‚ around and within cells. They control the movements in and out of cells‚ as well as protecting cells. They also allow different functions to occur. They have the same basic structure called the plasma membrane. All plasma membranes‚ around or inside cells have a same phospholipid bilayer structure. Phospholipids contribute to the flexibility of membranes and transfer

Unicellular organism From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search "Single-celled" redirects here. For prison cell assignment‚ see Single-celling. Valonia ventricosa is among the largest unicellular species. A unicellular organism‚ also known as a single-celled organism‚ is an organism that consists of only one cell‚ unlike a multicellular organism that consists of multiple cells. Historically the simple single celled organisms have sometimes been referred to as monads

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 because
