Unlike single-celled organisms that have direct contact with their external environment, most cells in a multicellular organisms do not have direct contract with their external environment. How do these cells acquire nutrients and eliminate wastes?
A) by active and passive transport between the basal lamina and the interstitial fluid
B) by active and passive transport between the basal lamina and the plasma
C) by active and passive transport between the intracellular fluid and the interstitial fluid
D) by active and passive transport between the intracellular fluid and the plasma
E) through gap junctions between the intracellular fluid and the plasma

Cells in multicellular organisms exchange nutrients and waste products with their external environment through active and passive transport between the intracellular fluid (inside the cell) and the interstitial fluid (the fluid that surrounds the cells within tissues). This process allows for the necessary exchange without direct contact with the external environment.
