Cereal is a grass (members of the monocot family Poaceae, also known as Gramineae)The seeds of several other plants, such as buckwheat, are also used in the same manner as grains, but since they are not grasses, they cannot strictly be called such cultivated for the edible components of their grain (botanically, a type of fruit called a caryopsis), composed of the endosperm, germ, and bran. Cereal grains are grown in greater quantities and provide more food energy worldwide than any other type of crop; they are therefore staple crops.
