Question

mistletoe plant has Green Leaves but still it is considered a parasite why ?

Answer 1

Mistletoe is classified as a partial parasite because it only depends on host for water and nutrients, rest of the job is being done by its green leaves.That's why mistletoe is called as partial stem parasite.

Mistletoe is not a total parasite it has got its own green leaf along with a structure called hastorium to suck or absorb the nutrients from nearby trees and plants and so it is called hemiparasite.
