प्रश्न
Explain why the grass in your lawn becomes greener if you add a little fertilizer to it, but it dies if you add a lot of it.

उत्तर
If a little fertilizer is added, it provides minerals and other nutrients so the leaves synthesize more chlorophyll and appear greener. If a lot of fertilizer is added, it forms a hypertonic solution resulting in plasmolysis and consequently wilting of parts of the plant. Ultimately the plant dies.
