Answer 1

Good Quality seeds are clean and healthy seeds free from infection and diseases.

With the help of good quality seeds, farmer gets high yield of food grains.

Activity To select Healthy seed for sowing:

1. If we are given wheat seeds for selection, then we need to pour all seeds in a bucket containing water.

2. Stir well

3. Most of the seeds will settle down at the bottom of the bucket and we an see few seeds float on water

conclusion :

--> Seeds which sink at the bottom of the bucket are healthy. Healthy seeds are heavy so they sink in water

--->on the other hand, seeds which are floating are light in weight because they will be partially eaten by pests or damaged by disease hence they are light and hollow. and hence float on water.
