Answer: The cell membrane invaginates and pinches off, creating a vesicle within the cell.
Explanation:
Endocytosis is an active transport mechanism, for particules to be transported, the plasma membrane of the cell invaginates, forming a pocket around the target particle. The pocket then pinches off, resulting in the particle being contained in a newly created intracellular vesicle formed from the plasma membrane.
