Whoa! Blueberries are berries, but not strawberries, according to Wiki:
“In the first image, only the blueberry is botanically a berry: blackberries are aggregate fruit composed of many drupelets, and strawberries are aggregate accessory fruits. Sloes, the fruits of Prunus spinosa, are drupes. Avocado fruit are described as either drupes or berries. Serviceberries, fruits of Amelanchier species, are pomes. Mulberries, the fruits of Morus nigra, are multiple fruits.” (WIKI)
