Differentiate between partial parasitic plants and total parasitic plants. Give one example of each?
Answers
Answer:
Explanation:
What is a Total Parasite
Total parasite is a parasite that completely depends on the host for all its requirements. Total parasitic plants are called holoparasites. They do not produce food and suck the sap from the host. Cuscuta (dodder) is the most common example of total parasitic plants. The leaves of the plant are reduced to minute scales. The specialized roots in holoparasitic plants are called haustoria.
example: Cuscuta, a Stem Holoparasite
Generally, endoparasite and ectoparasites are the two terms used to describe parasitic animals. Endoparasites live inside the body of animals while ectoparasites live on the body.
What is a Partial Parasite
Partial parasites are non-nutrient parasites that depend on the host for water or residence. Partial parasitic plants are called hemiparasites. Some examples of hemiparasites are mistletoe, which is an obligate stem hemiparasite, Indian sandalwood (Santalumalbum) Velvetbells (Bartsia alpina) Rattle plants (Rhinanthus) Indian paintbrush.
example: Mistletoe
Western Australian Christmas tree (Nuytsia floribunda) is another type of hemiparasite, which is an obligate root hemiparasite. Yellow rattle (Rhinanthus) is another facultative root hemiparasite.
