Inquiry Summary

Roots of some plants are modified for functions other than absorption and anchorage. These modified roots include those that store energy reserves for a plant as well as those that are involved in vegetative reproduction and obtaining oxygen. Parasitic plants obtain nutrients directly from other plants; many parasites have specialized root systems that tap into the tissues of their host. Aerial roots help adapt epiphytes to life aboveground.

Suppose you find one plant (plant A) attached to another (plant B). How could you tell if plant A was a parasite or just an epiphyte on plant B?
