What is difference between wheat wheat germ durum wheat semolina wheat?

Wheat refers to the grain itself, which is a staple food used in various forms, such as flour. Wheat germ is the nutrient-rich embryo of the wheat kernel, often removed during milling but valued for its health benefits. Durum wheat is a hard variety of wheat used primarily for pasta production due to its high protein content and gluten strength. Semolina wheat, derived from durum wheat, is coarsely ground and used to make pasta and certain types of bread, providing a distinct texture and flavor.
