Question

What are good quality seeds $?$ You are given a sample of wheat seeds. How will you select good, healthy seeds for sowing $?$

Answer 1

$\bullet$ Good quality seeds are clean and healthy seeds free from infection and diseases.

Selection of healthy seeds from a sample of given wheat seeds can be done in the following way :

$\bullet$ Put all the seeds in a beaker containing water and stir well.

$\bullet$ Most of the seeds will settle down at the bottom whereas some seeds will float on top.

$\bullet$ The seeds which sink at the bottom of the bucket are the healthy seeds.

$\bullet$ On the other hand, the seeds which float on water are the spoiled seeds.

$\bullet$ Seeds that have been damaged are hollow inside.

$\bullet$ As a result, the inner content becomes hollow and lighter and thus the seed floats, while good healthy seed sinks.
