Answer:
<u><em>Phospholipids are amphipathic. </em></u>
Explanation:
Amphipathic compounds can be described as compounds which have both polar and non- polar parts.
The phospholipids have polar heads. The tails of phospholipids are non-polar. The tails are made up of fatty acids which are insoluble in water. It is due to the amphipathic nature of phospholipids that the cell membranes are made up by it. The property of phospholipids helps the cell membrane to filter which molecules to let enter into a cell and which molecules should not be taken into the cell.
