No, rice is not a vegetable. Rice is actually a type of grain. It is the seed of a grass species called Oryza sativa or Oryza glaberrima, depending on the variety. Vegetables, on the other hand, refer to edible parts of plants such as leaves (lettuce), stems (celery), roots (carrots), or even flowers (broccoli). Rice, being a grain, is classified as a staple crop and is a primary source of nutrition for many people around the world.
