Morphology
chromoplast = chromo + plast
The parts are specialized scientific combining forms (chromo- 'color', -plast 'form/structure') that are not recognizable as independent everyday English words to a B1 learner, so the meaning is not derivable from common base words.
Etymology
Chromoplast joins chromo- 'color' and -plast 'to form', the same root you see in plastic. So a chromoplast is a 'color-formed' part of a plant cell that holds pigments and gives fruits and flowers bright colors.
