Arachis hypogaea, commonly known as the peanut, is a legume native to South America. It is unique because its flowers bloom above ground, but the pods develop underground. Peanuts are rich in protein, healthy fats, and various vitamins and minerals, making them a popular food source worldwide. Peanuts are cultivated in warm climates and are often grown in sandy soils. They play a significant role in agriculture, both as a food crop and as a source of oil. Additionally, peanuts are used in various products, including peanut butter, snacks, and cooking oil.
