False as the plasma cells differs from the B cell in having larger size and secreting the antibodies.
Further Explanation:
Plasma cells are formed from the antigen activated B-cells which is one of the type of leukocyte present in the secondary lymphoid organs like spleen and lymph nodes. Plasma cell starts to reside in the bone marrow after its formation. The plasma cells continues to generate the thousands of antibody against antigen that helps our body to provide immunity against the same.
An antibody which is also known as the<u> immunoglobulin</u> is a protective protein secreted in response to the entrance of foreign substance into the body of an organism. The antigens are recognized as foreign in an organism because the surface of the body has presence of molecules that is not recognized as the self-molecule by that organism.
<u>The antibody consists of two type of chain:
</u>
1. Heavy chain
2. Light chain
<u>Antibody</u> coats the antigen surface and then present the antigen to the <u>phagocytes</u>. There can be five classes of antigen that may differ in their constant region or the variable region.
The <u>B-cell</u> when encounters the antigen it divides and forms memory cell and a well differentiated cell called as plasma cell.
The <u>plasma cell</u> differs from the B-cell in having larger size and secreting the antibodies. The B-cell has antibodies present on their surface while plasma cell secretes these into the blood.
