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 1.BLANK. 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 2.BLANK.
1.Choices
-Endocytosis
-Exocytosis
-Diffusion
2.Choices
-The same for all of the cells
-Specific for the cells
-Never present on cells
Answers
Answer: The correct answers for the blank are 1) Endocytosis and 2) Specific for the cells.
White blood cells are the cells of the immune system. They help in protecting body from any pathogen like bacteria which can otherwise cause harm to the body. For this, they internalize the bacteria in the form of vesicles. This process is called as endocytosis.
The receptors present on the white blood cells are quite specific. Due to this, they recognize specific foreign particles. For instance, B and T cells are the cells of the adaptive immune system which have specificity for the foreign particles. Or in other words, specific foreign particles are recognized by specific white blood cell. This indicates that the receptors on these cells are quite specific.
Thus, the correct answer is 1) Endocytosis and 2) Specific for the cells.
