Question

Is Cuscuta a parasite?

Answer 1

Parasitism is a cooperative relationship between animal species in which one life type, the parasite, lives on or within another, the host, causing it damage, and is adapted to this lifestyle.

Complete answer:
Plant that receives all or part of its nutrition, without contributing to the benefit of the host, from another plant (the host) which in some cases causes extremes of host damage are called parasitic plants.
Cuscuta spp. (dodders) are plant parasites that interact with their host plants' vasculature to remove water, supplements, and even macromolecules. Until recently, there was no information on biologically significant interactions between have plants and Cuscuta , or between Cuscuta connect associated has. We show here that herbivore attack on one of the Cuscuta connect associated plants prompts quality articulation and expands the action of trypsin proteinase inhibitors, thereby increasing protection from creepy crawlies in other intact but Cuscuta -associated plants.
Cuscuta are parasitic plants. They need chlorophyll thus can't produce their own food through photosynthesis. They blossom with different plants, consuming their food and nutrients to develop, thus debilitating its host. It takes cover in a host cell. It's subject to food from another organic entity. Ectoparasites are parasites that dwell on a host organic entity's surface.

Note:
Another example of parasites is Tapeworm. Tapeworms are segmented flatworms that adhere to the insides of animals' intestines, including cows, pigs, and humans. They eat the host's partially digested food, depriving it of nutrients. Fleas bite their hosts, like dogs, and cause them to itch by sucking their blood and chewing their skin. Fleas, on the opposite hand, get food and a warm place. Barnacles, which survive whales' bodies, might not cause serious harm to their hosts, however they itch and are inconvenient.
