Question

The process by which a cell engulfs a foreign particle is known as:

endosymbiosis
phagocytosis
hydrolysis
membrane synthesis

Answer 1

Phagocytosis.

Step-by-step explanation:

Phagocytosis may be defined as the process by which the cell uses its plasma membrane to digest the foreign particles. The pathogens and cell debris are removed by the process of phagocytosis.

The foreign particle is directly engulfed by the immune cells in the process of phagocytosis. Phagocytosis provides the mechanism of protection from the pathogens and thus helps in the immune system of the body.

Thus, the correct answer is option (2).
