A drought plant is a type of plant that is able to survive in arid climates with little water. The term 'guar' is a four-letter word used to describe a drought plant, specifically the guar bean, which is native to India and Pakistan. It is an important crop for farmers in these regions, as it is able to withstand long periods of drought and still produce a harvest. Guar is also used in many food products, such as ice cream, as a thickening agent.
