What is the definition of pinocytosis

the ingestion of liquid into a cell by the budding of small vesicles from the cell membrane.Pinocytosis is the act of grabbing some liquid. The whole cell works during the process. It is not just some membrane proteins taking in a couple of molecules as in active transport.

Explanation:

Cells in the kidney can use pinocytosis to separate nutrients and fluids from the urine that will be expelled from the body. In addition, human egg cells also use it to absorb nutrients prior to being fertilized.

Pinocytosis sees the cell membrane wrap around a drop and pinch it off into the cell. The molecules inside of the newly created vesicles can then be digested or absorbed into the cytosol. Pinocytosis is a process that is happening all of the time. An amoeba may form the vesicles easily as it moves along.Pinocytosis is a form of endocytosis involving fluids containing many solutes. In humans, this process occurs in cells lining the small intestine and is used primarily for absorption of fat droplets.Also known as "cell drinking," the cell engulfs extracellular fluid, including molecules such as sugars and proteins. These materials enter the cell inside a vesicle. Epithelial cells in capillaries use pinocytosis to engulf the liquid portion of blood at the capillary surface.

Pinocytosis is a form of endocytosis involving fluids containing many solutes. In humans, this process occurs in cells lining the small intestine and is used primarily for absorption of fat droplets.A Pinocytic vesicle is a structure which helps in the Pinocytic process, where the small particles are bought into the cell, forming an infolding or invagination which in turn are suspended in the small vesicles. This process is also known as Cell Drinking.

Hope this helps :)
