Explanation / Answer

When they're exposed to water, they orient themselves in a double layer, so that the heads face out towards the water or inside of the cell and the tails face each other.
The plasma membrane is composed of a phospholipid bilayer that is rigid in nature.
Steroids are composed of four fused carbon rings.
Its function in the cell wall is to provide both flexibility and stability. Some steroids also function in cell-to-cell communication.
