Cell Membrane Coloring Worksheet The cell embrane is also called the ___ membrane and is made of a ____ Plasma, phospholipid bilayer The phospholipids have a ___ and two ____ Hydrophilic (water attracting) polar head and hydrophobic (water repelling) non polar tails The head of a phospholipid is made of an ___ and ___ Alcohol and phosphate The tails are chains of Fatty acids Phospholipids can move ___ and allow water and other smaller molecules to pass through into and out of the cell , aka diffusion Sideways Another type of lipid in the cell membrane is ____ that makes the membrane more ____ Cholesterol, fluid Embedded in the phospholipid bilayer are ____ that also aid in diffusion and in cell recognition Proteins Go all the through the bilayer Integral proteins Only on one side of the bilayer Peripheral protein Integral proteins are also called Channel proteins Four functions of the cell or plasma membrane: Selective transport, structural support, barrier/protection, and to maintain a balance between the cell and environment Phosphate heads ____ water Attract Helps maintain flexibility of membrane Cholesterol Involved in cell to cell recognition Glycoprotein and glycolipid Repels water Fatty acid tails Make up the bilayer Phosphate heads and fatty acid tails Help transport certain materials across the cell membrane Integral protein, peripheral protein, and glycoproteins what way does water move across membranes Down the concentration gradient Solute bigger outside Hypertonic Solute bigger inside Hypotonic 1/1
