Morphology

close + up

The meaning 'at or from a very short distance' is directly derivable from the spatial sense of 'close' (near) combined with 'up' as a directional/intensifying particle, so a B1 learner who knows those constituent senses will infer the MWE. This follows common English composition patterns (and parallels in other languages), making the expression immediately comprehensible and transparent.

Etymology

Close up comes from the image of bringing two edges together, like closing a book or stitching a wound, when you literally close up the gap so nothing is open. That's why it means 'to seal' or 'bring edges together'.
