Question

Specialized cells such as white blood cells interact with foreign particles in the body. A particular cell belonging to this category recognizes bacteria and forms a covering around it, pinching off the vacuole. The cell then performs . The foreign particles recognized by the particular type of cells differ from the ones recognized by another type of white blood cell. This situation indicates that the receptors are what?

Answer 1

Answer: The correct answers are 1) Endocytosis and 2) Receptors are specific for the cells.

White blood cells are specialized cells of the immune system. They play important role in protecting body from foreign agents like bacteria . For this, they recognize the bacteria and forms a covering around it, pinching off the vacuole. By this, the cell performs a process called as Endocytosis ( specifically phogocytosis).

The receptors present on the white blood cells are quite specific. Due to this, they recognize specific foreign particles. For example B- cells produce antibodies which bind to specific antigens ( foreign protein) and therefore mount specific immune response. In other words, specific foreign particles are recognized by specific white blood cell. This indicates that the receptors on these cells are specific.

Thus, the correct answer is 1) Endocytosis and 2)  Receptors are specific for the cells.

Answer 2

Answer:

The correct answers are endocytosis and the receptors are specific for the cells.

Explanation:

The white blood cells are the unique cells of the immune system. They perform an essential function of safeguarding the body from foreign agents like bacteria. In order to do so, they identify the bacteria and produces an envelope around it, pinching off the vacuole. With the help of this, the cell performs a procedure known as endocytosis.  

On the white blood cells, the receptors found are very unique, as because of them they identify the particular foreign particles, like B cells generate antibodies that combines with the particular antigens, and thus, impart specific immune response. Or it can be said, that specific foreign component is identified by the unique white blood cell, which shows that the receptors on these cells are unique.
