Final answer:
Phospholipids are amphipathic molecules with a polar head that is hydrophilic and a nonpolar fatty acid tail that is hydrophobic. The polar head faces towards water, while the nonpolar fatty acid tails face towards other fatty acid tails.
Step-by-step explanation:
Phospholipids are amphipathic molecules consisting of a polar head that is hydrophilic, or water-loving, and a nonpolar fatty acid tail that is hydrophobic, or water-fearing. The polar head faces towards water, while the nonpolar fatty acid tails face towards other fatty acid tails.
