Exocytosis is the process by which vesicles in the cytoplasm fuse with the cell membrane, releasing their contents into the cell's external environment. this is the form of transport used by a cell to dispose of large molecules. how does exocytosis a cell maintain its homeostasis?

Materials not required for the cell is given out by exocytosis. Waste materials, excess water and other undesirable substances are given out of the cell. Thus it helps in homeostasis

Cells must dispose of wastes in order to maintain their homeostasis.

Explanation: A cell's metabolic functions produce waste. If these wastes are not removed, they will build up in the cell and disrupt the cell's functions, so exocytosis helps a cell maintain its homeostasis by disposing of these wastes.
