Distinguish between parasites and partial parasites in plants, giving one example of each
Parasitism is a type of non mutual relationship between organisms of different species where one organism, the parasite, benefits at the expense of the other, the host. Traditionally parasite referred to organisms with lifestages that needed more than one host (e.g. Taenia solium). These are now called macroparasites (typically protozoa and helminths). The word parasite now also refers to microparasites, which are typically smaller, such as viruses and bacteria, and can be directly transmitted between hosts of the same species.
Plant that grow on other living plant and absorb food materials form them are called parasites. Some are total parasites and others are partial parasites. Partial parasites are green in color and can manufacture little food. They can depend entirely on the host plant. An example is the mistletoe.
A plant capable of photosynthesis but dependent on another plant for water and mineral nutrients, eg misdetoe. 2 A plant capable of living independendy but able to become parasitic in suitable circumstances, ie a facultative parasite.
Most of the diseases are caused by fungi bacteria and viruses. There are few seeds plants called flowering parasites (Phanerogams) which are parasitic on living plants. Some of these attack roots of the host, while some parasites on stem.
Some parasitic plants like mistletoe plant, which grow on trees such as mango or mahua, have green leaves and can synthesize their food. They take water and minerals from the host plants. They are known ad partial parasites
