Morphology
kingdom + Prokaryotae
This is a straightforward compositional taxonomic label: 'kingdom' (a taxonomic rank) combined with the name 'Prokaryotae' denotes the kingdom made up of prokaryotic organisms. If a learner knows the constituent meanings (including that Prokaryotae refers to prokaryotes), the overall meaning is directly derivable, though the taxonomic name itself is specialized and uncommon at B1.
Etymology
Kingdom Prokaryotae gets its name from Greek parts: pro- meaning 'before' and karyon meaning 'kernel' or 'nucleus'. It was used for organisms whose cells do not have a nucleus, so the name literally points to being 'before the nucleus'.
