Question

If there is high amount of fertilizer present in soil and it is deficient in water, then what will be the effect?

• A. Over growth
• B. Under growth
• C. No effect
• D. Wilting of plants

Answer 1

The correct option is D Wilting of plants

Water moves from a region of high water potential to a region of low water potential. Water potential depends on the number of water molecules in the system or solution. When soil is poorly watered but rich in fertilizers, the water potential of soil will be low. The soil solution will be hyperosmotic as compared to cell sap and the roots may not absorb water. This will lead to wilting.
