Question

How do some seeds become hollow and do they float on the surface of water?

Answer 1

The seeds that float on the surface of the water are the ones which have very low density and weight than the ones that sink.

This is generally because of the in-built bacteria or bugs which get inside these seeds, and eating it from the inside, making them hollow.

Answer 2

The answer is here,

Some seeds become hollow .because some bugs may enter into inside of the seed .And makes it hollow.

So, After the seed becomes hollow it's density decreases.Hence it floats on water.
