A plastid or cellular organelle that contains or produces calcium compounds or mineral deposits within plant cells.
From Greek 'gypsos' (chalk/mineral) and 'plastos' (formed), referring to a hypothetical organelle specialized in mineral accumulation or processing within plant tissue.
While this term is rarely used in modern botany, it represents an interesting historical attempt to explain how plants accumulate minerals—we now know plants do this through specialized cell structures, though not distinct organelles like this!
