Pinocytosis is literally translated from Greek as 'cell drinking.' It is one mechanism by which cells will take in fluids. Inside of cells we have the liquid portion called the cytoplasm, and each cell is surrounded by a semi-permeable cell membrane (allows some things in and out) made of lipids (fats).

you need to give an example like this
it occurs with most eukaryotic cells when the cell has to transfer a large protein or other soluble molecules across the membrane. pinocytosis is the invagination of the cell membrane taking in extracellular fluid and molecules required for homeostasis.
white blood cells that ingest foreign particles to rid the body of the infectious agents and/or to make antibodies against them. sometimes, pinocytosis is just the invagination of the membrane as a reservoir of the membrane.
bacteria use it to take in the extracellular fluid for the ions and other paticulate material
ameoba use it to transport sugars across the membrane
cells that line the kidney tubules use this to take in fluids and molecules from the fluid instead of letting them go out in the urine
the unfertilized egg uses it to take in nutrients prior to fertilization
