Morphology

orthotropic = tropic (semi-transparent) = ortho + tropic

Formed from 'ortho-' (straight/upright) + combining form 'tropic' (orientation), so the idea of upright orientation is recoverable though the biological usage is somewhat specialized.

Etymology

Orthotropic comes from the Greek parts ortho- meaning 'straight' and -tropic meaning 'turn' or 'direction', the same ortho- you see in orthodox. So an orthotropic shoot or stem grows 'straight' up along the plant's main trunk.
