Final answer:
A phospholipid molecule consists of a polar phosphate "head" and a non-polar lipid "tail." The head is hydrophilic, meaning it is attracted to water, while the tail is hydrophobic, meaning it repels water.
Step-by-step explanation:
A phospholipid molecule consists of a polar phosphate "head" and a non-polar lipid "tail." The head is hydrophilic, meaning it is attracted to water, while the tail is hydrophobic, meaning it repels water. This creates a unique structure in which the head and tail are arranged in a bilayer, with the hydrophobic tails facing inward towards each other and the hydrophilic heads facing outward towards the water.
