Cereals vs millets?
I was revising for my botny exam which is scheduled for tomorrow, and I suddenly realised i don't know why cereals like wheat,rice etc are given a different name than millets( pearl millet, finger millet etc) Best explanation I came across so far stated that cereals have larger grain size and are have more protein content whereas millets are nutritionally more dense and have smaller grains. Is this it?
I am not the best at botany and also had trouble relating to terms like awn,glume,auricles etc when talking about cereals.Any recommendations of books, articles, videos to help clear this up would be much appreciated.
Thank you!!
