need help? review these concept resources.

Explanation:

Phosphate heads are polar, hydrophilic (water-soluble) regions of phospholipids. In the cell membrane's lipid bilayer, they orient toward the watery cytosol inside the cell and the extracellular fluid outside, while the nonpolar fatty acid tails face the membrane's interior.

Answer:

water-soluble
lined up so they face the watery environments on the inside and outside of the cell
