The basic structure of plasma membrane is provided by:
Correct answer: D. Phospholipids
- A. Proteins
- B. Cholesterols
- C. Cytoskeleton
- D. Phospholipids
Explanation
The correct answer is Phospholipids because they form the bilayer that is the defining structure of the plasma membrane. This bilayer is composed of two layers of phospholipids, with hydrophilic (water-attracting) heads facing outward and hydrophobic (water-repelling) tails facing inward, creating a semi-permeable barrier.
