Fat absorption through the plasma membrane of epithelial cells .

Explanation:

1. Plasma membrane is semipermeable in which only selected particles are crossed. some particle can cross though simple diffusion and some requires specific protein channels through which they cross selectively.

2. Fat absorption through the plasma membrane of epithelial cells occurs by simple diffusion because lipids are simply able to penetrate the hydrophobic (that repel the water molecules ) fatty acid tails within the plasma membrane.
