What is grain?

What is grain? Did you know it is a dry fruit?

The definitions of grains and seeds are often confused. Words “grain” and “seed” have various definitions depending on the context.

The major difference is the biological one – the grain is a fruit which contains one seed inside, but looks like a seed because the fruit component is thin, dry and fused to a hard seed coat that looks just like a seed coat itself.

There are other differences, however, which are best represented by showing a table with various definitions and word uses.
