Morphology
trophozoite = tropho + zoite
The term is built from Greek combining forms ('tropho-' = feeding, '-zoite' = animal/stage) that are not standalone English words and the meaning is specialized scientific terminology not derivable by a typical B1 learner from known English bases.
Etymology
Trophozoite comes from Greek parts: tropho- meaning 'nourish' or 'feed' and -zoite meaning 'animal' or 'living thing'. So a trophozoite is the active, feeding stage of a tiny parasite, the time when it grows and eats inside its host.
