A process of cellular ingestion by which the plasma membrane folds inward to bring substances into the cell.

en′do·cyt′ic (-sĭt′ĭk), en′do·cy·tot′ic (-sī-tŏt′ĭk) adj.
en′do·cy·tose′ (-tōs′) v.


(Biochemistry) the process by which a living cell takes up molecules bound to its surface


(ˌɛn doʊ saɪˈtoʊ sɪs)

the transport of particles into a living cell by the movement of a filled vacuole that has formed from the folding inward of the part of the cell membrane on which the particles rest (disting. from exocytosis).
Compare phagocytosis.
en`do•cy•tot′ic (-saɪˈtɒt ɪk) adj.
