Morphology
polyploidy = polyploid (semi-transparent) = poly + ploid + y
The noun is a regular -y nominalization of the adjective 'polyploid', so the derivation itself is straightforward.
Etymology
Polyploidy comes from the parts poly- meaning 'many' (as in polygon) and -ploid meaning 'fold' or 'layer'. So polyploidy literally means 'many-fold', which helps you remember it refers to cells that have 'many' sets of chromosomes instead of the usual two.
