WebbThe contents of a cell are separated from its environment by a plasma membrane, which consists largely of two layers of phospholipids -- or a phospholipid bilayer. The bilayer can be thought of as a sandwich that encircles the cell, with a nonpolar, water-fearing spread between pieces of bread. The "spread" is ...
WebbThere are two important parts of a phospholipid: the head and the two tails. The head is a phosphate molecule that is attracted to water (hydrophilic).The two tails are made up of fatty acids (chains of carbon atoms) that aren’t compatible with, or repel, water (hydrophobic).The cell membrane is exposed to water mixed with electrolytes and other … WebbQuestion 5. 30 seconds.
