Why Cuscuta is a total stem parasite?
Cuscuta wraps around the whole host plant and stays attached to it until the host dies. The vegetative part of Cuscuta is its stem and thus it is a total stem parasite.
How Cuscuta take nutrition from a tree?
Cuscuta reflexa (Amarbel) is a yellow tubular plant twisting around the stem and branches of a tree. It does not have chlorophyll and hence cannot make its food. They climb on other trees known as host plant and absorb the readymade food. Therefore plants like Cuscuta are known as parasite.
