When a cell membrane engulfs fluid droplets it is called:
A)diffusion
B)receptor-mediated endocytosis
C)phagocytosis
D)pinocytosis
E)osmosis

Question

Quizplus · Accepted Answer

Pinocytosis is the process by which a cell takes in small droplets of fluid by engulfing them with its cell membrane. This is often referred to as "cell drinking," as it is a way for cells to bring in liquids, small molecules, and other substances that cannot pass freely through the cell membrane. Diffusion involves the movement of molecules from an area of high concentration to an area of low concentration, while receptor-mediated endocytosis and phagocytosis are both types of endocytosis that involve the cell taking in larger particles or molecules. Osmosis involves the movement of water molecules across a selectively permeable membrane.
