Answer:

(a) Crop

Crop may be defined as the same kind of plants that are grown on the large scale.

(b) Preparation

Before growing crops, preparation of soil is done. In this process, turning and loosening steps of the soil is done. It allows the roots to penetrate deep into the soil.

(c) Float

The damaged seeds are light in weight. That is why they float on water whereas the fresh seeds are heavy in weight so they easily settle down in the bottom.

(d) Water and nutrients

For a health crop, we need a proper sunlight, water and nutrients. If the deficiency of these things occurs then the crop should be weak.
