Upon finding a host, it sinks its fangs (known as haustoria) into the vascular system of its victim and drinks its water and nutrients. Dodder then grows and reattaches until it covers all nearby host plants in a tangled mat of orange stems.
If conditions are suitable, a fungus spore will germinate after landing on a host plant and form a tiny root system known as a haustoria.
Because it does not have a root system, mistletoe feeds on a host tree using root-like projections called haustoria.
