Evolutionary biologists, using pea roots, studied if plants can actually hear water sources and seek them out. The roots sought out a flowing water source that was open as well as surprisingly, one that was hidden behind plastic. Over the years plants have evolved a way to “hear” water sources by sensing vibrations made by the water. Once they seek out the source, they can root down into the area to nourish themselves with a continued water supply.

Key Takeaways:

• Scientist tested a hypothesis that plants can actively seek out water.
• They showed that the roots grow towards the water source no matter where it is placed.
• To detect the water plants utilize moisture gradients in the soil to direct the roots towards the water.

“Vegetarians often turn to plant-based diets because they fear killing sentient beings.”
