A plasma B cell is a B cell that has been activated to proliferate and produce antibodies against a specific antigen. A memory B cell is a B cell that lives a long time after an infection to provide long lasting immunity against that specific antigen. They both originate from the same B cell in your secondary lymph system. Once activated the specific B cell will proliferate into plasma B cells and memory B cells.

A mature B cell that mass produces antibodies is called a plasma cell. Plasma cells are differentiated B cells that are specialized for producing large quantities of antibodies to help fight infections.
Well firstly an antigen presenting cell like dendritic cell or macrophage is needed. Secondly you also need a T cell that is complementary to the B cell. B cell will only become plasma cell when it receives the full signal 1. Stimuli: CD4 from T cell interacting with BcR/antigen complex on B cell 2. Co-stimuli: CD40L (CD154) on T cell interacting with CD40 on B cell This interaction allows T cell to secrete IL4, this binds to IL4R on B cell thus receive signal for proliferating and differentiating.
A being quite more active than B. Cell A is part of an organ that does more work than Cell B. Cell B does less work than Cell A.

The surface immunoglotulin that serves as the B-Cell antigen receptor (BCR) has two roles in B-cell activation. First, like the antigen receptor on T cells, it transmits signals directly to the cell's interior when it binds antigen. Second, the B-Cell antigen receptor delivers the antigen to intracellular sites where it is degraded and returned to the B-cell surface as peptides bound to MHC class II molecules.
