BI Lab 5

plasma membrane physical barrier that separates the cell interior from the environment and regulates substances passing into or out of the cell
lipids and fats main components of the plasma membrane and of cell organelle membranes
bilayer lipid molecules form a ________ with protein molecules of various types distributed throughout the lipid bilayer
diffusion the process by which molecules move about by inherent random motion and become evenly mixed or dispersed
equilibrium exists when the molecules become uniformly distributed
concentration gradient exists when molecules are not evenly distributed
temperature, pressure, concentration, and molecule size variables that affect diffusion
selectively permeable some substances pass through more readily than others
impermeable completely prevents the passage of those molecules into or out of the cell
dialysis the diffusion of a dissolved solute through a selectively permeable membrane
osmosis diffusion of water through a selectively permeable membrane
solutes particles in a solution
isotonic (iso=same) two solutions that have the same concentrations of solutes
hypertonic (hyper=higher) solution contains a higher concentration of solutes than another solution
hypotonic (hypo=lower) solution contains a lower concentration of solutes in comparison to another solution
monosaccharide one sugar
polysaccharide large molecule composed of many sugars
vacuole surrounded by the vacuolar membrane
vacuolar membrane is selectively permeable
turgor pressure presses the cytoplasm against the cell wall
turgid cells with turgor pressure
plasmolysis the shrinkage of the cytoplasm away from the cell wall
