What characteristic of phospholipids allows them to form the double layer seen in cell membranes?

Question

Quizplus · Accepted Answer

Phospholipids have a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail, making them amphipathic molecules. This characteristic allows phospholipids to arrange themselves in a double layer, with the hydrophilic heads facing outward towards the water environment and the hydrophobic tails facing inward towards each other, creating a barrier between the inside and outside of the cell.
