Question

One day I saw my mother put some gram seed in a vessel and pour some water on them. After a few minutes some seeds started to float on top. I wonder why some seeds float on water!

Answer 1

It's a simple process by which we can separate bad quality seeds. For this we simply need to add water to the seeds and the one which floats is the bad one. Mark it as best pls

Answer 2

these seeds float as they are damaged or hollow. this makes them light weighted and therefore float. the seeds which sink are good and healthy seeds. this method is used by farmers to select disease free, healthy seeds.
