Surface Forms

plasma cell singular
plasma cells plural

Morphology

plasma + cell

The compound 'plasma cell' transparently signals a type of cell associated with plasma (blood), so a B1 learner who knows 'plasma' and 'cell' would likely infer it is a blood-related cell. However, the specific immunological role (a differentiated B lymphocyte that produces antibodies) is specialized and not predictable from the constituents alone, so the expression is only partly compositional.

Etymology

Plasma cell gets its name from the idea that this cell makes and releases antibodies into the blood's plasma, the liquid part of the blood. So the name highlights its job: a cell that makes antibodies 'to fight infection'.
