Detailed explanation-1: -The other type is pinocytosis (“cellular drinking”), which involves the ingestion of fluid and solutes via small pinocytic vesicles (about 100 nm in diameter). Most eucaryotic cells are continually ingesting fluid and solutes by pinocytosis; large particles are most efficiently ingested by specialized phagocytic cells.

Detailed explanation-2: -Pinocytosis, also known as cell drinking, is common in plant and animal cells. During pinocytosis, the cell takes in substances from the extracellular fluid that it needs to function. These include things like water and nutrients. Receptor-mediated endocytosis is a specialized type of pinocytosis.

Detailed explanation-3: -Pinocytosis is an active, energy consuming process where extracellular fluid and solutes are taken up into a cell via small vesicles. It is a type of endocytosis, which refers to the uptake of substances by a cell.

Detailed explanation-4: -Classification of Endocytosis Pinocytosis (“pino” means “to drink”) is a process by which the cell takes in the fluids along with dissolved small molecules. In this process, the cell membrane folds and creates small pockets and captures the cellular fluid and dissolved substances.

Detailed explanation-5: -Pinocytosis was discovered by Warren Lewis in 1931 and is also known as fluid-phase endocytosis. Pinocytosis is an example of endocytosis, a cellular process in which substances are brought inside a cell. Other types of endocytosis include phagocytosis and receptor-mediated endocytosis.
