Why are cell membranes composed primarily of hydrophobic molecules?

Consider the function of the cell membrane: The cell membrane's primary function is to act as a selective barrier, controlling the movement of substances in and out of the cell. The hydrophobic core of the membrane prevents the free passage of polar and charged molecules, which are typically soluble in water.

Evaluate the importance of the hydrophobic nature: The hydrophobic nature of the cell membrane is crucial for maintaining the integrity of the cell, preventing the dissolution of the membrane in the aqueous environment, and ensuring that the cell can maintain its internal conditions.
