Dodder (Cassytha spp., Cuscuta spp.) Are you suggesting this orchid is a parasite? Species of Striga alone are estimated to cost billions of dollars a year in crop yield loss annually, infesting over 50 million hectares of cultivated land within sub-Saharan Africa alone. The smallest angiosperm is Mistletoe Rafflesia Wolfiella Wolffia Answer: 4 Q3. Science > Biology > Botany> Morphology of Plants > Modification of Roots In this article, we shall study the modification of roots for the purpose of food storage, respiration, support, etc. 2001. Using the resources in the seed endosperm, dodder is able to germinate. Cuscuta (dodder) is the most common example of total parasitic plants. Roots in some plants change their shape and structure and become modified to perform functions other than absorption and conduction of water and minerals. The International Parasitic Plant Society: Photo gallery, Calladine, Ainsley and Pate, John S. 2000. Distance from the host and stored nutrients are some of the problems, and the host's defenses are an obstacle to overcome. D. Monotropa.

Some families consist mostly of parasitic representatives such as Balanophoraceae, while other families have only a few representatives. Parasitic plants are classified depending as to the location where the parasitic plant latches onto the host and the amount of nutrients it requires. 8. Once germinated, the plant has 6 days to find and establish a connection with its host plant before its resources exhaust. Partial parasites are non-nutrient parasites that depend on the host for water or residence. These chemical cues are a variety of compounds that are unstable and rapidly degraded in soil and are present within a radius of a few meters of the plant exuding them.
