Final answer:

Fat-soluble vitamins, like vitamin A, enter cells by dissolving in the lipid bilayer, crucial for absorption and utilization in the body.


Explanation:

Fat-soluble vitamins like vitamin A can pass through the plasma membrane due to their lipid solubility. They enter cells by dissolving in the lipid bilayer, unlike water-soluble substances that require specific transport mechanisms.

This ability of fat-soluble vitamins to easily cross plasma membranes is crucial for their absorption and utilization in the body, as seen with the absorption process of vitamin A through chylomicrons in the intestine and its storage in the liver.

Understanding how these vitamins move across membranes provides insights into their bioavailability and potential accumulation, impacting overall health.
