Answer:
Antibodies and memory B cells.
Step-by-step explanation:
The germinal center of lymphatic nodules has many cells types including B cells and follicular dendritic cells. The follicular dendritic cells bind to the entered antigen and represent it to the B cells. The proliferation of B cells produces plasma cells and memory B cells. The plasma cells further divide and produce a group of cells that differentiate into antibodies specific to the entered antigen.
