Chapter 4: Q.15 (page 125)

The process by which a cell engulfs a foreign particle is

known as:

a. endosymbiosis

b. phagocytosis

c. hydrolysis

d. membrane synthesis

Short Answer

Expert verified

Phagocytosis is a process by which cell engulfs a foreign particle.

Step by step solution

01

Explanation

Endosymbiosis is a symbiotic relationship where one organism lives within other organisms and mutually helps each other. Hence, option a is wrong.

Hydrolysis is a process in which water is used to break down a compound. So, option c is wrong as well.

It is the process of formation of cell membranes, it takes place in Endoplasmic Reticulum. This option is wrong too.

Phagocytosis is a type of endocytosis i.e. ingestion of molecules via active transport. It happens when a cell tries to eliminate something, such as a virus or an infected cell, and it's commonly used by immune system cells. Thus, option b is correct

02

Conclusion

Phagocytosis is a process in which the cell engulfs a foreign particle to eliminate it from body.
