Berries and Nuts

Berries are defined as fleshy fruits from a single flower with one ovary, exemplified by grapes and blueberries. Interestingly, many foods we label as nuts, such as almonds and peanuts, do not fit the botanical definition of nuts, which include a hard shell and an internal seed. True nuts, like hazelnuts and acorns, retain their seeds within an inedible outer layer, highlighting the complexity of fruit classification.
