Solution:

Concept:Bajra seeds:Bajra is the important millet grown in India.Though these are known as coarse grains, they have very high nutritional value.It is a rain-fed crop mostly grown in moist areas which hardly need irrigation.Bajra grows well on sandy soils and shallow black soil.Major Bajra producing States are Rajasthan, Uttar Pradesh, Maharashtra, Gujarat and Haryana.It uses to make chapatis.Explanation:Journey of a Bajra seed from field to plate:Harvesting:?Harvesting is the cutting of a crop after it is matured.The Bajra seeds peak from the field during harvesting.Threshing:?After harvesting Bajra seeds threshing process is done.This process is used to separate the Bajra grain from stalks.In this process, the stalks are beaten to free the Bajra grain seeds.Winnowing:?The next process is winnowing.In this method, components are separated from the mixture.Winnowing is used to separate heavier grain and lighter husk components of a mixture by wind or by blowing air.Grinding:?After the grain is separated from the husk, the grinding process is done.In this process, grains are put in a Chakki for grinding for making powder.Kneading:The next process is called kneading.Where water is mixed with powder grain for making dough.Rolling and Roasting:?In the next process, small balls are taken from the dough.Then they are rolled for making Chapaties.After that, the Chapaties are put on Tawa for roasting.Finally, these Chapaties are ready for the plate.Thus, the correct journey of a Bajra seed from field to plate is Harvesting, Threshing, Winnowing, Grinding, Kneading, Rolling, and Roasting.
