The survival of terrestrial plants depends upon the capacity of roots to obtain water and nutrients from the soil. Directed growth of roots in relation to a gradient in moisture is called hydrotropism and begins in the root cap with the sensing of the moisture gradient.

For most plants survival depends upon the capacity of root tips to sense and move towards water and other nutrients in the soil. ... These results showed that hydrotropism is amenable to genetic analysis and that an ABA signaling pathway participates in sensing water potential gradients through the root cap.

The objective is to observe if watering the plants differently affects the roots grow differently. Another objective is to see if hydrotropism really exists.
