Question

Quizplus · Accepted Answer

Plasma is the liquid component of blood that carries blood cells and other substances. Similarly, cytosol is the liquid component of cytoplasm that carries organelles and other substances. Inclusions, organelles, and proteins are all components of cytoplasm, but they do not fulfill the comparison to plasma in the same way as cytosol. Serum is the liquid component of blood that is left when blood clots and is devoid of blood cells and clotting factors, so it does not compare to cytoplasm at all.
