Schrink: Encogerse

Crenation: A process resulting from osmosis in which red blood cells, in a hypertonic solution, undergo shrinkage and acquire a notched or scalloped surface

Active transport

Endocytosis: the taking in of matter by a living cell by invagination of its membrane to form a vacuole

Pinocytosis: the ingestion of liquid into a cell by the budding of small vesicles from the cell membrane.

Phagocytosis: the ingestion of bacteria or other material by phagocytes and amoeboid protozoans.

Phagosome: a vacuole in the cytoplasm of a cell, containing a phagocytosed particle enclosed within a part of the cell membrane.
Osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes
