plant (plant) any multicellular eukaryotic organism that performs photosynthesis to obtain its nutrition; plants comprise one of the five kingdoms in the most widely used classification of living organisms. plant a member of the vegetable kingdom; living things characterized by absence of locomotion, absence of special senses, and feeding only on inorganic substances. abortigenic plant plants that cause abortion include Pinus, Cupressus and Astragalus spp. plant alkaloids see alkaloid. annual plant one that completes its life cycle within one year. A winter annual plant germinates in the fall, overwinters as a seedling and flowers and seeds in spring. The dominant grazing species in the early spring. Examples would be many mustard weeds of disturbed places incriminated in the congenital hypothyroid dysmaturity syndrome in foals. plant awns sharp, long processes attached to seed casings of plants, mostly grasses; important causes of skin and oral lesions in grazing animals, and to housed animals when fed hay containing the plants. biennial plant one that completes its life cycle in two years, generally germinating and growing in the first year and flowering, fruiting and subsequently dying in the second year. plant eating both dogs and cats may eat grass; indoor animals sometimes eat ornamental plants, some of which are poisonous. plant edemagens plant substances that cause edema in animals, e.g. 3-methyl indole, produced in the rumen from tryptophan. plant hormones organic substances produced by plants which are extracted and used as herbicides or plant growth stimulants. Some of them cause long-term ill health in animals if drunk in large quantities. perennial plant one that completes its life cycle over more than two years. plant poisoning the list of poison plants is very large and it is necessary to know the suspect plant's botanical name to begin an effective search for information about it. In order to exert an effect on an animal the plant has, in most cases, to be eaten. There are a few plants that exert a toxic effect by inhalation or by skin contact. plant protein the proteins in plants. Common, protein-rich plants include alfalfa, the oilseed meals, e.g. soyabean, cottonseed and linseed meals, clover, the legume seeds, e.g. peas, beans. teratogenic plant plants that cause congenital defects include Lupinus, Lathyrus, Leucaena, Nicotiana, Conium, Astragalus, Oxytropis, Veratrum, Vicia, Salsola spp. plant toxins phytotoxins, elaborated by plants, in some cases incorporating an inorganic element, e.g. selenocompounds, and in some cases present in the plant in an inert state, requiring an additional ingredient, e.g. ruminal fermentation to activate it.
