Detailed explanation-1: -The membrane proteins and the lipids in these vesicles provide new components for the cell’s plasma membrane, while the soluble proteins inside the vesicles are secreted to the extracellular space. The fusion of the vesicles with the plasma membrane is called exocytosis.

Detailed explanation-2: -Exocytosis is the process by which cells move materials from within the cell into the extracellular fluid. Exocytosis occurs when a vesicle fuses with the plasma membrane, allowing its contents to be released outside the cell.

Detailed explanation-3: -Exocytosis is a process in which a vacuole fuses with the cell membrane, releasing its contents to the outside of the cell. The membrane of the vesicle then becomes part of the cell’s plasma membrane, and the contents may enter a duct or the bloodstream.

Detailed explanation-4: -Exocytosis is the fusion of secretory vesicles with the plasma membrane and results in the discharge of vesicle content into the extracellular space and the incorporation of new proteins and lipids into the plasma membrane.

Detailed explanation-5: -Phagocytosis is a special form of endocytosis in which large particles such as microorganisms and dead cells are ingested via large endocytic vesicles called phagosomes.
