<h3><u>Answer</u>;</h3>
C. Phospholipids form a selectively permeable structure
<h3><u>Explanation</u>;</h3>
- Phopholipids are types of lipids which are amphipathic molecules, that is they have both non-polar and polar end.
- They are fundamental building blocks of cellular membranes and are the major part of surfactant.
- <em><u>Phospholipids are selectively permeable that is they allow some molecules but not others to pass across it. The phospholipid bilayer is permeable to small polar molecules and nonpolar molecules. They bilayer is impermeable to larger polar molecules and ions</u></em>.
Answer:
