Nuts are made of the seed and the fruit, where the fruit does not open to release the seed. Most seeds come from fruits, and the seeds are released from the fruit. But nuts (such as hazelnuts, hickories, chestnuts and acorns) have a stony fruit wall which keeps the seed inside.
In common speaking, many so-called nuts, like pistachios and Brazil nuts, are not nuts in a biological sense. Everyday common usage of the term often refers to any hard-walled, edible kernel as a nut.
Types of nutsEdit
Types of nuts include the oak, hickory, chestnut, stone-oak, birch, and hazelnut. The peanut, coconut, almond, macadamia, pistachio, pecan, walnut and cashew are not true nuts, but treated as one in cooking.
