biology
Quick Summary
Hydrotropism is a biological response where plant roots grow towards a source of water. This is a type of tropism, which is a directional growth or movement in response to a stimulus.12
In hydrotropism, the orienting factor is water or water vapor. This allows plants to seek out the moisture they need to survive. Other forms of tropism include phototropism (response to light) and geotropism (response to gravity).312
