Question: what is the main difference between pinocytosis and phagocytosis?
Answer: Pinocytosis is a type of endocytosis involved in the transport of particles sized 0.5 µm or less. Phagocytosis involves the formation of pseudopodia (false feet) for the intake of molecules. Pinocytosis intakes the particles via invagination and formation of pockets in the cell membrane.
