Question

give reason why on soaking seeds in water some seeds float on the water?give answer fast because it is my holiday homework

Answer 1

some of the seeds sink in water and some of them floats on water this is because the seeds that sinks in water are not damaged and can be used for agricultural practice and the seeds that float means they are totally damaged and can be used, this is very old method to check the seed that if they are damaged or all right. similarly when we put egg in a bowl and pore water if the eggs would seep than they are all right and are eatable but they float on water it means they are cannot be eaten.

Answer 2

"This is one among the oldest methods to check whether the seeds has the compatibility for production of crop. If seed is perfect, it will absorb water and swallow, therefore, it will sink in water.

Whereas the seed which do not absorbs water will not swallow, therefore, it will not sink in water.

Hence, such seeds, which float on the surface of the water, will be considered to be damaged and cannot be used for production of crops."
