Since it has no chlorophyll, it is also dependent on the host for its organic supply. It is in fact a complete parasite. A marked feature is the absence of foliage leaves in the vegetative region of the Dodder. There are not even any cotyledons on the embryo. This is to be connected with the parasitic nutrition ; there.
