Raspberry

Both raspberries and blackberries can be any colour from white through yellow, orange, pink, red, and purple to black, the difference between being one of structure. The fruit, though called berry, is technically an etaerio of druplets (a cluster of small fruits with stones). The etaerio grows from a core called a receptacle. When a blackberry is picked the receptacle remains inside the etaerio. When a raspberry is picked the etaerio comes away from the receptacle, which remains on the plant as an obvious white, conical structure. The absence of a core in the picked fruit makes raspberries softer and juicier to eat than blackberries.
