Same species
Black pepper and white pepper both come from Piper nigrum. Harvest maturity and removal or retention of the outer fruit layers produce their different appearances and flavor profiles.
Berry
Bananas are botanical berries, while strawberries are aggregate accessory fruits. The distinction depends on how a flower becomes a fruit, not on sweetness, size or the name on a grocery label.
Legume
Peanuts are legumes, in the same plant family as peas and beans, rather than true botanical nuts. Their unusual feature is that the flowers develop above ground but the pods mature below it.
