Endocytosis is the transport of macromolecules, large particles, and small cells into eukaryotic cells

Occurs through engulfment by, and vesicle formation, from the plasma membrane.

Phagocytosis and pinocytosis are types of endocytosis.
Endocytosis

In receptor-mediated endocytosis, a specific receptor protein on the plasma membrane binds to a particular macromolecule.

In exocytosis, materials in vesicles are secreted from the cell when the vesicles fuse with the plasma membrane.
