Holo-parasites are those parasites that completely depend on their host for their nutrition and all their essential needs, such as water and minerals. They lack any chlorophyll and do not undergo photosynthesis, that is, they cannot produce their own food and rely on their host for it. Examples of holo-parasites include Rafflesia, Dodder, Orobanche, and Cuscuta.
Hemi-parasites, on the other hand, are partially photosynthetic, that means they can produce their own food through light energy but still depend on their host for nutrients such as nitrogen and water, which they absorb through root-like structures called haustoria. Hemi-parasitic plants have leaves, stem, root system but depend on the host for their whole or part of the survival. Examples of hemi-parasites include Mistletoe, Indian sandalwood, and Witchweed.
