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).

Detailed explanation-2: -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-3: -Pinocytosis is the process in which cells take in liquid material from their external environment; literally ‘cell drinking’. Liquid is enclosed in vesicles, formed by invagination of the plasma membrane. These vesicles then move into the cell and pass their contents to endosomes.

Detailed explanation-4: -Phagocytosis is the taking in of large food particles, while pinocytosis takes in liquid particles. Receptor-mediated endocytosis uses special receptor proteins to help carry large particles across the cell membrane.
