IMMUNOLOGY

Detailed explanation-1: -When a naive B cell encounters an antigen that fits or matches its membrane-bound antibody, it quickly divides in order to become either a memory B cell or an effector B cell, which is also called a plasma cell. Antibodies can bind to antigens directly.

Detailed explanation-2: -Activated B cells divide rapidly and repeatedly to form clones of? memory cells and plasma cells.

Detailed explanation-3: -When cytokines are produced, the B-cell is activated to produce more antibodies against the antigen. The activated B-cell begins to divide, and it becomes an antibody-producing cell called a plasma cell. The plasma cell produces immunoglobulin that is secreted on the cell surface.

Detailed explanation-4: -B cells differentiate into plasma cells that produce antibody molecules closely modeled after the receptors of the precursor B cell. Once released into the blood and lymph, these antibody molecules bind to the target antigen (foreign substance) and initiate its neutralization or destruction.

Detailed explanation-5: -B cells differentiate into memory cells and plasma cells.
