what is hydro tropism
the growth or turning of plant roots toward or away from moisture.
This is of biological significance as it helps to increase efficiency of the plant in its ecosystem.The process of hydrotropism is started by the root cap sensing water and sending a signal to the elongating part of the root. Hydrotropism is difficult to observe in underground roots, since the roots are not readily observable, and root gravitropism is usually more influential than root hydrotropism.[2] Water readily moves in soil and soil water content is constantly changing so any gradients in soil moisture are not stable.
