Which transport mechanism can bring whole cells into a cell?
pinocytosis
phagocytosis
facilitated transport
primary active transport

phagocytosis is a correct answer.

Explanation:

Phagocytosis is a mechanism by which cell with help of its plasma membrane ingest large particle or whole cells and then it is targeted to lysosomes for the enzymatic deactivation.phagocytosis process is very specific because cell bind only to that item, which they want to engulf.

Phagocytosis plays a major role in removing the pathogen in a multicellular organism.

This mechanism is performed by professional phagocytes such as neutrophils, dendritic cells and macrophages and also by nonprofessional phagocytes such as retinal epithelial cells.

Thus phagocytosis is a transport mechanism can bring whole into a cell.
