What is the primary role of cholesterol in the cell membrane?

Step 1: Understand that cell membranes are made of a double layer of lipids (fats).
Step 2: Know that these lipids can move around, making the membrane flexible.
Step 3: Realize that if the membrane is too fluid, it can become weak and lose its structure.
Step 4: Learn that if the membrane is too rigid, it can become inflexible and not function properly.
Step 5: Recognize that cholesterol is a special type of fat that fits between the lipids in the membrane.
Step 6: Understand that cholesterol helps to keep the membrane at the right balance of fluidity, making it neither too rigid nor too fluid.
