Fat and oxygen are the substances that moves
passively from the lipid part of the membrane, other substances which moves
from the membrane are steroids and oxygen.
<span>The membrane which separates the cell from the
outside environment is cell membrane and phospholipid is the major lipid or
primary type of lipid which is used in the cell membrane.</span>

A phospholipid is made of glycerol, two the fatty acid tails, and a phosphate-linked head group. More unsaturated fatty acids it means less tightly packed phospholipids its results to the greater membrane fluidity. Unsaturated fatty acids are naturally occurring, meaning that the remaining hydrogen is on the same side of the molecule and result in a bending of the hydrocarbon chain.
