Plants are affected and, in extreme circumstances killed, by the same range of parasites and pathogens that cause diseases and disorders in animals and man, though the number of parasites in the various groups is probably different. (It's difficult to be certain as the presence of some pathogens or parasites is difficult to detect without sophisticated diagnosis and there are a great many plant species.)
The commonest pathogens are fungi (mainly microfungi) and viruses, followed by bacteria and phytoplasmata (primitive bacteria with small cells and lacking a cell wall).
Depending on your definition of parasite, many arthropods (insects, mites) and nematodes feed on and in plants causing various degrees of damage and, incidentally, often acting as vectors or facilitators for the ingress of the microorganisms listed above.
Epiphytic and parasitic plants grow on plants. It helps support the host plant.
Parasitic plants such as dodder, broomrape, and mistletoe steal nutrients and water from their host plants through specialized structures called haustoria. These parasitic plants tap into the host plant's vascular system to extract what they need for survival, often at the expense of the host plant's growth and health. This can weaken the host plant and hinder its ability to photosynthesize and produce its own food.

Adaptation of parasitic plants allows them to obtain essential nutrients and water from other plants, enabling them to survive in challenging environments. By tapping into the resources of host plants, parasitic plants can thrive in habitats where traditional plant growth may be limited. Despite their negative impact on host plants, parasitic plants play a role in nutrient cycling and ecosystem dynamics.
Parasitic plants slide feeding tubes into the host plant and suck out the nourishing juices of the host plant.
Parasitic plants have specialized features that enable them to extract nutrients and water from their host plants. They often possess structures called haustoria, which penetrate the host's tissues to establish a connection for nutrient transfer. Many parasitic plants lack chlorophyll and do not perform photosynthesis, relying entirely on their hosts for sustenance. Additionally, they may exhibit modified leaves or stems that facilitate their attachment to the host and enhance their parasitic lifestyle.
Parasitic plants do not prepare their own food. These plants take it from the host plants generally through haustoria.
Parasitic plants depend on other organisms, typically host plants, for their nutritional needs by tapping into their vascular systems. They extract water, minerals, and nutrients directly from the host’s tissues through specialized structures called haustoria. This allows parasitic plants to thrive in environments where they might otherwise struggle to obtain sufficient resources, often at the expense of the host's health. As a result, parasitic plants can significantly impact the growth and survival of their hosts.
Worms can be harmful if they are ingested and become parasitic in the body. These worms can actually create holes in the intestines or the stomach and kill the host.
A parasite lives on or in a host, which it depends on for survival. This relationship can be simply parasitic, where the host does not benefit from the parasite. This relationship may also be symbiotic, in which both the parasite and the host benefit.
Parasitic flatworms have to have a host. A free-living one doesn't.
becaz they don't leave the host until they absorb all the nutrients from the host parasites leave the host only after the death of host organisms.
