Storage organs are specialized structures in plants that store nutrients and energy. Common examples include tubers, like potatoes, and bulbs, such as onions. These organs help plants survive during unfavorable conditions, like winter or drought, by providing a reserve of food. In addition to plants, some animals also have storage organs. For instance, the liver in mammals stores glycogen, a form of energy, and vitamins. These organs play a crucial role in maintaining energy balance and supporting overall health by ensuring that essential nutrients are available when needed.
