Final answer:
Phospholipids in the cell membrane play a crucial role in maintaining the structure and function of the cell.
Step-by-step explanation:
Phospholipids are a major component of the cell membrane, forming a bilayer that provides structural support and serves as a barrier to control the movement of substances in and out of the cell. Their hydrophilic (water-loving) heads face outward towards the aqueous environment, while their hydrophobic (water-fearing) tails face inward, creating a stable barrier. This unique arrangement allows phospholipids to regulate the transport of molecules, maintain cell integrity, and facilitate cell signaling and recognition.
