How would you describe the structure of the cell membrane to a kid?
Interesting. What is the purpose of the fat molecules in the membrane?
The fat molecules, or lipids, provide a barrier that separates the inside and outside of the cell. They are arranged in a double layer, with the hydrophobic (water-fearing) tails pointing inward and the hydrophilic (water-loving) heads pointing outward. This arrangement helps to maintain the structure and function of the membrane.
