trophotropism singular

Morphology

trophotropism = tropism (semi-transparent) = tropho + tropism

The meaning is compositionally 'movement/response toward nourishment', but it uses the technical combining form 'tropho-' which is not a familiar standalone English word for average learners.

Etymology

Trophotropism joins two Greek parts: tropho- meaning 'food' (think of atrophy, when muscles 'waste away') and -tropism meaning 'turning toward'. So, trophotropism is a movement or growth by a living thing that 'turns toward' a source of food or nutrients.
