This may be for one of these reasons: *It has [[pollen]] that makes them sneeze *It [[spread]]s [[seed]]s that will grow quickly *The [[root]]s go too far under the ground and can cause damage to houses or pipes *The [[root]]s [[spread]] quickly *The plant has [[poison]]ous [[berry|berries]] *The plant has [[liquid]] ([[sap]]) in it that can hurt a person's [[skin]] If someone is [[farm]]ing a plant and it then moves outside the farm, the plant may then be called a weed. Some [[plant]]s are very hard to stop once they start growing. These are called [[Invasive species|invasive]] weeds. Weed can also be a name for any [[wild]] [[plant]], one that people do not use for anything and invading their space. == References == {{reflist}}{{biology-stub}} [[Category:Types of plants]]
