What property makes phospholipids ideal building blocks for cell membranes?
Papessa [141]

Answer:

<u> They have hydrophilic heads and hydrophobic tails.</u>

Explanation:

Phospholipid membranes are comprised of a chain of lipids. These typically are arranged in a bilayer; the hydrophilic lipid heads are polar, and face outwards, while the hydrophobic tails are polar facing inwards.

The membranes are selectively permeable, and only allow the movement of small, non-polar molecules through the bilayer.
