Morphology

biogenous = biogen (semi-transparent) = bio + gen + ous

The adjective is formed with the scientific combining form bio- and the suffix -ous, but the full meaning depends on a specialized classical derivation rather than everyday English.

Etymology

The word biogenous comes from bio- 'life' and -genous 'produced by', the same bio- as in biology and the same root you see in generate ('make'). So a biogenous material is literally 'produced by life', like sediments made from shells and tiny sea creatures.
