 (pĭn′ə-sĭ-tō′sĭs, -sī-, pī′nə-)
n.
Introduction of fluids into a cell by invagination of the cell membrane, followed by formation of vesicles within the cell.
[Greek pīnein, to drink; see pō(i)- in Indo-European roots + cyt(o)- + -osis.]

pinocytosis

(ˌpaɪnəʊsaɪˈtəʊsɪs)
n
(Biology) biology a method by which a cell takes in and absorbs fluid by the process of invagination followed by tightening and closing off of the cell membrane

(ˌpɪn ə saɪˈtoʊ sɪs, ˌpaɪ nə-)

n.
the endocytic transport of fluid into a living cell by the formation in the cell membrane of a separate tiny vacuole around each droplet.
[1931; < Greek pín(ein) to drink + -o- + -cyte + -osis, on the model of phagocytosis]
