Answer:

Immune system of the body helps in fighting with the infectious agents that are foreign for the body. So the immune system protects us from infection.

When any foreign substance(antigen) comes in the body B-lymphocyte recognize it by binding the antigen through its receptor. After recognizing the antigen, B cell divides into antibody-producing plasma cell and memory cell.

Antibodies produced by plasma cells help in destroying the antigen by getting the antigen recognized by phagocytic cells or by complement activation.

B cells are antigen-presenting cell which present antigen to T cell and then T cell activates and produce chemicals that kill the antigen. Therefore the immune system has many immune cells that activate when an antigen comes in the body. This is how the immune system functions.

Butoxors [25]

Answer:

Ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles.

Explanation:

The endomembrane system in eukaryotes has divided the cell organelles into the structural and functional unit. This system plays an important role in the protein processing, its sorting and transport of protein.

The protein is prepared from the plasma cells. The antibodies is made on the ribosomes by the translation process. From the ribosomes, it will move to the endoplasmic reticulum for the glycosylation and protein folding. Then it moves to the golgi for the further protein packaging and processing. With the help of the vesicles it moves to its destination part in the cell.

Thus, the correct answer is option (d).
