Explanation:

The cell membrane's main structure is a phospholipid bilayer. Phospholipids have a hydrophilic head and hydrophobic tails, forming the basic framework of the membrane. Carbohydrates are present in small amounts (as glycoproteins/glycolipids for cell recognition), cholesterol is a minor component for membrane fluidity, and water is not a main structural component of the membrane itself.
