Which statement describes the phospholipid bilayer of a cell membrane?

This statement is incorrect because the fatty acid tails of phospholipids are actually hydrophobic, meaning they repel water. Their hydrophobic nature is essential for forming the bilayer structure of the cell membrane, keeping the tails away from the water while the hydrophilic heads interact with the surrounding aqueous environment.

The glycerol component of phospholipids is not hydrophobic; rather, it is part of the hydrophilic phosphate head. The hydrophilic nature of the phosphate head allows it to interact favorably with water, which is crucial for the formation and stability of the cell membrane.

This statement is false because charged phosphate groups are inherently hydrophilic due to their polar nature, allowing them to form hydrogen bonds with water molecules. This characteristic is vital for the structural integrity of the phospholipid bilayer, as it facilitates interactions with the aqueous environments inside and outside the cell.
