Understand the key terms: Exocytosis, Pinocytosis, Phagocytosis, and Endocytosis. These are all processes related to the movement of materials in and out of cells.
Exocytosis is the process by which cells move materials from within the cell into the extracellular space. This involves the fusion of vesicles with the plasma membrane to secrete substances.
Pinocytosis and Phagocytosis are types of Endocytosis, which is the process of taking materials into the cell. Pinocytosis involves the ingestion of liquid into the cell, while Phagocytosis involves the ingestion of larger particles or cells.
Endocytosis is the general term for the process of taking substances into the cell, which is the opposite of Exocytosis.
Identify that the process involving the secretion of materials at the plasma membrane is Exocytosis, as it specifically refers to the expulsion of substances from the cell.
