In binomial nomenclature, a good many (don't want to say all, as I doubt that's true) of the terms are in Latin or are Latin-based. Are the words used to describe kingdom, phylum, class etc etc put in the Nominative Plural or in the Genitive Singular?
For example, "plantae". Should this be "Plants" or "Of Plant"?
Again, incredibly random, and my command of Latin (or lack thereof) means that I can't just look at other examples and be able to tell.
Thanks to whoever can help satisfy my curiosity!
