Cellular membranes are a phospholipid bilayer. This means that they have:
Recall that phospholipids have a hydrophobic end and a hydrophilic end and that when placed in water they will orient themselves accordingly (5.11 pg 79). This is the basis for the plasma membrane of a cell.The cell membrane consists of a phospholipid bilayer with embedded proteins.ecall that phospholipids have a hydrophobic end and a hydrophilic end and that when placed in water they will orient themselves accordingly (5.11 pg 79).
