For her science fair project Jacqueline decided to do an experiment with plants. She planted pea seeds
in two pots. One pot had very nutrient-rich soil, the other had nutrient-poor soil. After letting her pea
plants grow for a month she pulled up the plants and looked at their roots. The pea plants growing in
the nutrient-rich soil had very few root hairs, the pea plants growing in nutrient-poor soil had many
root hairs. What is a likely explanation for Jacqueline's findings?

Answer:

The roots of the plant growing in the nutrient-rich soil could find its nutrient without much penetrating in the soil. Hence, it did not have to develop longer roots in search of the nutrients. On the contrary, the plant which was growing in nutrient-poor soil did not have much abundance for the required nutrients from the soil. As a result, the roots of this plant grew longer in search of nutrients from the soil.
