Explanation:
Detailed explanation-1: -The fatty acids of most natural phospholipids have one or more double bonds, which introduce kinks into the hydrocarbon chains and make them difficult to pack together. The long hydrocarbon chains of the fatty acids therefore move freely in the interior of the membrane, so the membrane itself is soft and flexible.
Detailed explanation-2: -The cell wall is a tough, flexible and sometimes rigid layer that surrounds some cells e.g., plant cells. It surrounds the cell membrane and provides these cells with structural support and protection.
