Morphology

peroxisome = peroxide (opaque) = peroxide + some

Although formed from 'peroxide' + the combining form '-some' ('body'), the term is a specialized scientific coinage and its meaning is not derivable by an average learner from the components.

Etymology

Peroxisome comes from peroxide and Greek soma meaning 'body', so it literally means a 'peroxide body'. That's why a peroxisome is a small body inside cells that breaks down peroxide and other harmful chemicals to keep the cell safe.
