What process involves a cell surrounding material with its plasma membrane to take in material through a vesicle?

• A. Exocytosis
• B. Endocytosis
• C. Diffusion
• D. Filtration

Answer: (B)

The process that involves a cell surrounding material with its plasma membrane to take in material through a vesicle is called endocytosis. In endocytosis, the plasma membrane invaginates, or bends inward, to envelop extracellular material, forming a vesicle that brings the material into the cell. This is critical for various cellular functions, such as nutrient uptake, removal of debris, and communication through signaling molecules. Endocytosis can be further categorized into various types depending on the nature of the material being taken in, such as phagocytosis (cell eating) for large particles, and pinocytosis (cell drinking) for liquids and small molecules. This mechanism is distinct from exocytosis, where materials are expelled from the cell. In contrast to diffusion, which involves the passive movement of molecules across membranes, and filtration, which typically involves the movement of fluid and solutes through a membrane based on pressure, endocytosis is an active process that requires energy to facilitate the formation of the vesicles and the transportation of materials into the cell.
