Final answer:
Exocytosis is the process by which a vesicle within the cell moves to the cell membrane, fusing with it and releasing its contents to the outside of the cell.
Step-by-step explanation:
The process that involves a vesicle forming of liquid in the cell and then moving to the outside of the cell is known as exocytosis.
This active transport process is crucial for various cellular functions including exporting materials out of the cell, such as proteins, waste, or toxins, as well as incorporating membrane proteins and lipids into the plasma membrane.
The vesicle migrates through the cytoplasm to the cell membrane, where it fuses with the membrane, and the contents of the vesicle are released into the extracellular space.
