All grains are seeds, but not all seeds are grains. Beans, nuts, and “seeds” are also all seeds!
By definition, a seed is a “flowering plant’s unit of reproduction, capable of developing into another such plant”. Grains (cereals) grow from the seeds of grasses. Nuts grow from the seeds of trees. And seeds (pseudocereals or other “seeds”) grow from the seeds of non-grasses.
