Phospholipid molecule is an amphipathic molecule.

Answer

### Step-by-Step Solution:

1. **Understanding Amphipathic Molecules**:
- An amphipathic molecule is one that has both hydrophilic (water-loving) and hydrophobic (water-repelling) parts. This dual nature allows it to interact with both polar and non-polar substances.

2. **Structure of Phospholipids**:
- Phospholipids consist of a hydrophilic head and two hydrophobic tails. The hydrophilic head is typically made up of a phosphate group, which is polar and interacts well with water. The hydrophobic tails are made of fatty acids, which are non-polar and do not interact with water.

3. **Arrangement in Biological Membranes**:
- In aqueous environments, phospholipids arrange themselves into a bilayer. The hydrophilic heads face outward towards the water, while the hydrophobic tails face inward, away from the water. This arrangement is crucial for the formation of cell membranes.

4. **Conclusion**:
- Since phospholipids have both hydrophilic and hydrophobic components, they are classified as amphipathic molecules. This property is essential for their role in forming cell membranes, allowing cells to maintain a distinct internal environment.
