Morphology
chromosome = chromo- + -some (opaque) = chromo + some
Although analyzable into Greek combining forms meaning 'colour' + 'body', the modern scientific sense 'threadlike DNA structure carrying genes' is not derivable by an average B1 learner from those parts.
Etymology
The word chromosome comes from Greek parts chroma ('color') and soma ('body'); the chroma part is the same idea as in chrome because early scientists saw these threads take up color dyes and look like tiny colored bodies under a microscope. So a chromosome is literally a 'colored body' - the threadlike part in the cell nucleus that carries genes.
