Exocytosis
Verified step by step guidance
1
Understand the concept of cellular transport: Cellular transport refers to the movement of substances across the cell membrane. It can be active (requiring energy) or passive (not requiring energy).
Learn about phagocytosis: Phagocytosis is a type of active transport where a cell engulfs large particles, such as food or pathogens, by wrapping its membrane around the particle to form a vesicle. This process is often used by immune cells like macrophages.
Differentiate phagocytosis from other transport types: Pinocytosis involves the ingestion of liquids and small molecules, facilitated diffusion is a passive transport mechanism using protein channels, and exocytosis is the process of expelling substances from the cell.
Visualize the process of phagocytosis: The cell membrane extends outward to surround the particle, forming a structure called a phagosome. The phagosome then fuses with a lysosome to digest the particle.
Apply the knowledge to the question: Since the problem asks about a cell taking in a large particle by engulfing it with its membrane, the correct type of transport is phagocytosis.
