Question

how do phospholipids help to make the very important cell membranes or lipid bilayers in plasma membranes? ready? enter your answer here.

Explanation:

Phospholipids have a hydrophilic (water - loving) head and hydrophobic (water - fearing) tails. In an aqueous environment, they spontaneously arrange into a bilayer. The hydrophilic heads face the aqueous environments inside and outside the cell, while the hydrophobic tails are sandwiched in the middle, creating a barrier that is selectively permeable, controlling the movement of substances in and out of the cell.

Answer:

Phospholipids have hydrophilic heads and hydrophobic tails. They arrange into a bilayer in an aqueous environment with heads facing the water and tails in the middle, forming a selectively - permeable barrier for the cell.
