Quizplus · Accepted Answer

All three processes - pinocytosis, receptor-mediated endocytosis, and phagocytosis - are mechanisms by which materials from the extracellular fluid can cross the plasma membrane and enter a cell. Pinocytosis involves the non-specific uptake of fluids and small solutes by the cell, while receptor-mediated endocytosis and phagocytosis are selective processes that occur when specific molecules or particles bind to receptors on the cell surface. Therefore, choice D, "all of the above" is the best answer.
