Morphology
flame + cell
The compound clearly names a kind of biological 'cell', so a B1 learner would recognize it as a type of cell and might infer a flame-like appearance from 'flame'. However, the specific excretory function and the technical reason for the name are domain-specific and not predictable from the plain meanings of 'flame' + 'cell', making the relation only partially clear.
Etymology
The name flame cell comes from the tiny hairs inside the cell that wave like a little flame when people look under a microscope. That's why flame cell is used for the special cell that helps 'remove' 'waste' and extra water in flatworms.
