Detailed explanation-1: -The process of ingestion of liquid food particles or materials by the cells through the plasma membrane is called pinocytosis while the ingestion of solid food particles is known as phagocytosis.

Detailed explanation-2: -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-3: -Pinocytosis refers to intake of liquid by an animal cell by the cellular invagination whereas phagocytosis means intake of solids by an animal cell. Pinocytosis is also called cell drinking whereas phagocytosis is called cell eating.

Detailed explanation-4: -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. Phagocytosis and receptor-mediated endocytosis are other types of endocytosis.

Detailed explanation-5: -pinocytosis, a process by which liquid droplets are ingested by living cells.
