IPA: /hɔˈstɔːriəm/
KK: /hɔˈstɔrɪəm/
A special part of a parasitic plant that grows into another plant to take nutrients from it.
The dodder plant uses its haustorium to extract water and nutrients from the host plant.
Haustorium is derived from the Latin root "haurire" (meaning to draw or to drink). The suffix "-ium" is often used in Latin to denote a place or a condition. Thus, haustorium refers to a structure or organ that draws nutrients or fluids, particularly in plants or parasitic organisms.
Think of 'drawing' ('haurire') nutrients or fluids, which helps you remember that a haustorium is a structure that draws in resources.
