Question

In wheat, the edible part is
A. Whole seed
B. Whole fruit
C. Endosperm
D. Endosperm and embryo

Answer 1

Wheat is a grass species that is widely cultivated as a cereal grain and is used as a portion of staple food worldwide. All of the wheat species come under the genus Triticum and the most common one is Triticum aestivum. The various processing stages remove the extraembryonic layers and expose the inner edible part.

Complete answer: Wheat is a worldwide grown grass crop for its seed which is used as a staple diet source. There are various wheat species and the most common is T.aestivum. The wheat crop undergoes several processing stages to get the final product. It is the most grown crop all over the world. Wheat serves as a key source of carbohydrates. Caryopsis is the fruit of wheat. The seed coat and the pericarp of the fruit are fused and are not distinguishable. The seed coat is the protective covering of the seed and the pericarp is the maternal nutritious tissue which is usually fleshy. Both of these are removed during the processing to expose the inner seed. The seed is the edible part of the wheat crop. The endosperm is the inner nutritious tissue of the seed and the embryo is the innermost part of the seed. The endosperm helps in providing nutrition to the growing embryo during germination. Both of these make the whole seed.
So, from the above discussion, we can conclude that the correct answer is option A.

Note: Wheat is the leading source of vegetable protein in human food globally. It has 13% protein content but it is relatively low in providing essential amino acids to the body. It is generally eaten as a whole grain. It is the source of dietary fiber and multiple nutrients.
