What do we call the roots of some orchid plants, which hang in the air and absorb moisture from it?

Answer: [B] Epiphytic Roots

An epiphyte is a plant that grows harmlessly upon another plant (such as a tree) and derives its moisture and nutrients from the air, rain, and sometimes from debris accumulating around it. Epiphytes differ from parasites in that epiphytes grow on other plants for physical support and do not necessarily negatively affect the host.
