B cells are produced in the bone marrow and then move to the spleen to continue to mature. After that, they move throughout the bloodstream and lymphatic system (the system liking all of your lymph nodes.)

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.
The plasma membrane of an Elodea cell is located just beneath the cell wall. It acts as a barrier, regulating the movement of substances in and out of the cell.
a. Basal cell carcinoma arises in the basal cell layer of the epidermis. b. Malignant melanoma arises from melanocytes located in the basal layer of the epidermis. c. Squamous cell carcinoma arises in the squamous cells of the epidermis, which are found in the upper layers of the epidermis.
Antibodies are bound to the surface of a B cell. These antibodies serve as receptors that allow the B cell to recognize and bind to specific antigens. This binding process helps initiate the immune response by activating the B cell to differentiate into plasma cells that secrete antibodies.
Cell A does more work than Cell B
Cell B does less work than cell A.
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.
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.
the cell wall is located on the outer edge of the cell
In a nerve cell, the nucleus is located in the cell body.

Blood antigens A and B are located on the surface of red blood cells, while the Rh antigen (Rh factor) is also found on the surface of red blood cells. These antigens determine an individual's blood type.
The plasma membrane of an Elodea cell is located just beneath the cell wall. It acts as a barrier, regulating the movement of substances in and out of the cell.
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.
The cell membrane is located inside the cell wall. it is located in both plant and animal cells composed of fats made up with protein which holds all of the cell pieces and fluids inside the cell and keep nasty stuff away from the cell.
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.
